15 Celebs Who Stole Someone Else's Man

As we all know, love usually doesn't last forever in Hollywood. Stars seem to be constantly ending romantic relationships just to start a new relationship moments later. The tabloids are always filled with celebrity dating drama, and it can be hard to separate fact from fiction. What we do know for sure is that there are a few celebrities that notoriously broke up a relationship in order to be with someone. Despite having an endless dating pool and knowing that they would receive a lot of negative press for stealing someone else's man, these stars swooped in and got in between some pretty established couples. Some even ruined marriages and destroyed relationships while the other woman was pregnant! In some cases, celebrities have stolen their so called friend's boyfriend. I guess all is fair in love and war.

Here are 15 celebrities that didn't let someone being in a relationship stop them from pursuing their desires:

15 Angelina Jolie

Angelina Jolie may be the queen of man stealing. We all know that Brad Pitt was married to Jennifer Aniston when the Mr. & Mrs. Smith costars first started their romance. Brad and Jennifer were married for five years before Angelina got in between them. Many people were shocked when they found out Brad was leaving all American Jenn for wild card Angelina. Before starting her relationship with Brad, Angelina had already stolen another star's man. Billy Bob Thornton was engaged to actress Laura Dern when he started a relationship with Angelina. When asked about the affair, Laura has stated, "I left our home to go and make a movie and while I was away, my boyfriend got married and I never heard from him again." Ouch! Not only did Angelina steal Billy Bob, she also got a tattoo of his name and wore a vial of his blood on a necklace.

14 Gisele Bundchen

Gisele Bundchen may be one of the most beautiful women on the planet, so we are not surprised that she used her good looks to steal all-star football player Tom Brady from his girlfriend at the time, actress Bridget Moynahan. Not only did Tom leave his girlfriend for the model, he also left his unborn child. Yep, Bridget was pregnant when he dumped her. Tom and Gisele met through a mutual friend, and the model claims they haven't spent a day not speaking to one another since then. At least it seems that Tom and Gisele are truly in love. The couple has remained steady since 2006 and are now happily married. Despite breaking up, Tom and Bridget do remain friendly since they are raising a child sort of together. Bridget claims there is no drama between her and Gisele, although it has been tough being a single mom.

13 LeAnn Rimes

LeAnn Rimes shocked fans and ruined her good country girl image when she decided to steal Real Housewives of Beverly Hills star Brandi Glanville's husband, Eddie Cibrian. LeAnn was also married when the two met on the set of the Lifetime movie, Northern Lights. Paparazzi snagged a picture of the duo snuggling up in a restaurant while they were still married to other people. It was not soon after the photos leaked that LeAnn filed for divorce from backup dancer Dean Sheremet. Eventually, LeAnn and Eddie got married, but they definitely caused drama when they first started their relationship - they were all over the tabloids for months. When asked about the affair, LeAnn says "I take responsibility for everything I have done. I hate that people got hurt, but I do not regret the outcome." We are not sure how Brandi feels about LeAnn today, but reportedly she has forgiven her.

12 Claire Danes

Claire Danes may be the quintessential pretty girl next door, but she's also a man stealer. Mary-Louise Parker and Billy Crudup were dating for six years before Claire got in between their relationship. To make matters worse, Mary-Louise was also 7 months pregnant. Claire and Billy met on set while shooting Stage Beauty, and their connection was apparently strong enough for Billy to leave his pregnant girlfriend. The relationship only lasted a few years before they parted ways and Claire moved on to Hugh Dancy. Although Mary-Louise was dumped, we're happy that she went on to have a kick a$$ career. She also published a memoir 12 years after the split called "Dear Mr. You" in which she addresses how she felt about being left by her long time boyfriend just before giving birth. Needless to say, she wasn't thrilled. Clarie also admits she was a 24-year-old who wasn't necessarily thinking about consequences when she pursued Billy.

11 Britney Spears

We were all surprised when super successful pop star Britney Spears decided to marry backup dancer Kevin Federline, but we were even more shocked by the fact that Kevin left his pregnant girlfriend, actress Shar Jackson to be with her. Kevin and Shar already had a child together and were engaged. Kevin left his family for Britney, and eventually started a new family with the singer. Kevin and Britney did get a divorce a few years later, and Kevin is now married to former volleyball player Victoria Prince - they have two children of their own. Of course Britney is still rich and famous, but how is Shar doing? On an episode of Celebrity Fit Club, Kevin told Shar he was sorry about leaving her while she was pregnant, and she seemed to accept his apology. The two even hugged it out. Shar continues to be an actress and it looks like she's moved on from the drama.

10 Amber Heard

Johnny Depp was in a relationship with French actress and singer Vanessa Paradis from 1998 to 2012, which is when Amber Heard entered the picture. Vanessa and Johnny seemed like a pretty solid couple. They had two children together, and were often seen together on red carpets. When Johnny met Amber on the set of The Rum Diary, he immediately fell for the actress who is 23 years younger than him. He claims he could not get her off his mind, which is a problem when you are in a committed relationship. He left Vanessa pretty abruptly, and married Amber a few years later. Johnny and Amber were not shy about their relationship, and were often spotted snuggling up together in public. After what seemed like blissful marriage for a few years, Johnny and Amber were caught in a nasty divorce that included allegations of domestic abuse. It's safe to say he was better off.

9 Elizabeth Taylor

Elizabeth Taylor was one of the first celebrities to get married numerous times, 8 times to 7 different men to be exact. Her fourth husband, singer and actor Eddie Fisher, was married to the legendary Debbie Reynolds when Elizabeth got in between them. Debbie and Eddie were together for a few years and had two children together, including Star Wars actress Carrie Fisher. Elizabeth's late husband, producer Mike Todd, was also Eddie's best friend, which made things even more complicated. At the time of the scandal in 1959, Debbie was very popular and loved by the public, so many people started to dislike Eddie. The scandal had a big negative impact on his career. NBC canceled his television series and he was dropped by his music label. A few years after getting married, Elizabeth and Eddie got divorced. Eddie went on to get married three more times, and Debbie also got married two more times.

8 Denise Richards

Actress and model Denise Richards made headlines when she reportedly stole one of her best friend's boyfriend. Denise started a fling with Bon Jovi guitarist Richie Sambora, who was still in a relationship with actress Heather Locklear at the time. Denise was recently divorced from actor Charlie Sheen with whom she had two children. Heather and Richie were married from 1994 to 2007, and had a child together. Although Richie claims he never cheated on his wife, many sources report his relationship with Denise is what ruined their marriage. Richie and Denise did go public as a couple just a few months after his divorce was finalized. Needless to say, Denise and Heather are no longer besties, although it was reported that Heather forgave the pair. The couple did not last too long and had an on again off again relationship for a few years before calling it quits.

7 Evan Rachel Wood

Actress Evan Rachel Wood and rocker Marilyn Manson had an up and down relationship from 2007 to 2010 that began with an affair. When they first met at a party, they both felt attracted to each other, despite their 19 year age gap. Marilyn then wrote a song for her called "Heart Shaped Glasses" and had her star in the music video. It would have been a romantic start to their relationship if he wasn't already married to burlesque dancer Dita Von Teese. The rocker clearly has a type. After two years of marriage, the two separated mainly due to his affair with Evan. When asked about the divorce in an interview, Dita said "I wasn't supportive of his partying or his relationship with another girl. As much as I loved him, I wasn't going to be part of that." Marilyn did propose to Evan a few years into their relationship, but the two decided to part ways.

6 Paris Hilton

One Tree Hill fans were thrilled to see actors Chad Michael Murray and Sophia Bush get married in 2005. Unfortunately for them, the marriage lasted only five months, and many sources say Paris Hilton is to blame. Paris and Chad met on the set of House of Wax and reportedly hooked up during the time of filming. Paris was also seeing someone at the time - Backstreet Boy Nick Carter. To make things even more awkward, Sophia and Chad had to continue working together on the show after their divorce. Chad went on to date another One Tree Hill crewmember, who he proposed to after just a few months of dating - he actually proposed the same year that he got divorced from Sophia. They never did get married although they dated for seven years. Sophia got over the break up pretty quickly and decided to focus on her career. Looking back, she feels like they were too young to have gotten married - she was only 22 at the time.

5 Gabrielle Union

Gabrielle Union and Dwyane Wade are now happily married, but they definitely had a drama filled relationship before getting hitched. The basketball player was married to his high school sweetheart, Siohvaughn Funches, when he first met the actress at a Super Bowl party. Gabrielle and Dwyane claim they didn't begin their relationship until after his separation, but his ex-wife claims she's part of the reason for their split. Dwyane's divorce was nasty and Siohvaughn made many terrible claims and filed several lawsuits during the process. She wound up getting a large sum of money and their house as part of the settlement. Gabrielle stayed by Dwyane and the two became a public couple. The pair decided to take a break due to career demands, and during that time, Dwyane wound up getting another woman pregnant. Despite this, Gabrielle decided to give Dwyane another shot, and the two got back together and were engaged shortly after.

4 Khloe Kardashian

Khloe Kardashian had a rough relationship with basketball player Lamar Odom, and her fans have been hoping that she finds true love. The reality star recently started dating NBA player Tristan Thompson, who just became a father. We're not positive if Tristan and his ex, Jordan Craig, split because of his relationship with Khloe, but we're sure Khloe and Tristan were already an item while she was pregnant. Khloe also was in the press for being a man stealer for dating French Montana, who she publicly dated shortly after rapper Trina. Trina has admitted in interviews that she was hurt when she found out about their relationship, especially because she considered Khloe a friend. In a radio interview, Trina said “I mean it's a little surprising when you're living with somebody that they're running around with somebody else.” If Khloe and Tristan don't last, we're not sure whose man she'll snatch up next.

3 Mia Farrow

Mia Farrow has had her share of heartbreak - after all, Woody Allen did leave her for her daughter, but she's also responsible for causing a divorce. Musician Andre Previn was married to singer and songwriter Dory Previn for 10 years before his affair with Mia caused him to leave her. During their marriage, the couple had recorded many award winning songs. Dory apparently had no idea the divorce was coming, and was so shocked by the affair that she had a mental breakdown. She spent months in a psychiatric hospital where doctors encouraged her to write down what she was feeling. She wound up making an album with lyrics she wrote down during her stay in the hospital. One of her most popular songs, "Beware of Young Girls", is about the affair. Mia was just 23 when she started her relationship with Andre who was 15 years older than her.

2 Kristen Stewart

Kristen Stewart was already a famous actress when she began having an affair with little known director Rupert Sanders. The two worked together on the movie Snow White and the Huntsman and at the time, Rupert was married to British model and actress Liberty Ross. The pair got hitched in 2002 and had a son and a daughter together, but that didn't stop Rupert from pursuing a relationship with Kristen, who is 19 years younger than him. Paparazzi caught him cheating on Liberty with Kristen and released pictures of the two kissing, which ultimately led to his divorce. Kristen was also still in a relationship with her Twilight co-star Robert Pattinson when the affair took place, which led to their relationship ending as well. Kristen and Rupert's relationship didn't last very long, and the actress eventually came out as being bi-sexual. She is currently dating model Stella Maxwell.

1 Kylie Jenner

Kylie Jenner's relationship with rapper Tyga is constantly in the press. She was pretty young when they first started dating, and Kardashian family friend Blac Chyna had just given birth to his son. Apparently, Kylie was the reason for Blac and Tyga ending their engagement. To make things more complicated, Blac started dating Rob Kardashian. Of course this caused a ton of family drama since his sisters did not really want to hang out with Kylie's man's ex-girlfriend. After lots of social media insults between the Kardashians and Blac, things got even weirder when Rob and Blac got engaged and had a child together. It seems like Kylie and Blac worked out their differences, but we are not too sure how long their newly rekindled “friendship” will last. Tyga and Kylie are reportedly no longer together after years of dating, and Rob and Blac called off their engagement and broke up.
