By

Jude Law, Justin Timberlake, Liam Hemsworth
Oh boy. Even before some of these celebs married, they were caught up in cheating scandals!

Cameron Diaz recently made a media splash after claiming that everyone will get cheated on at some point.

While we think that's an extreme assumption, these cheaters are proving that she may not be entirely incorrect. Are you surprised by any of these 10 celebs who cheated on their girlfriends?

Jude Law
Jude was engaged to Sienna Miller in 2005 when he famously cheated with his children's nanny, Daisy Wright. After the tabloids exploded with news of his infidelity, the actor made a public apology to his fiancee. The two never wed but Sienna says they have moved on from the incident. "I'm great friends with him and with his children. I love them, madly."

Justin Theroux
Before Jennifer Aniston came along, Justin Theroux was living with his girlfriend of 14 years, Heidi Bivens. When Jen and Justin met on the set of Wanderlust in 2010, he was still living with Heidi. But rumors soon swirled that Justin was cheating on Heidi, although Heidi's mom denied his involvement with Jen. When J + J finally came out as a power couple, Heidi had just moved out of the NYC apartment she shared with Justin. Lines are blurry, but it looks like Jen took a play from the Angie handbook.

Justin Timberlake
Although Jessica and Justin were on-again/off-again, heavy rumors suggested that while still dating, Justin had an affair with Olivia Munn after meeting at a MySpace event. Supposedly, he sent her messages claiming that he and Jessica were over. To this day, JT denies the claim and Olivia has made no statement about the incident. Justin and Jessica married two years after the scandal.

Liam Hemsworth

Miley's enjoyed her fair share of fun this past year, but did former fiancé Liam Hemsworth stray with January Jones before Miley began acting out? Tabloids went crazy after rumors started flying about Liam and January spending the night together after the 2013 Oscars. Although it was never confirmed, Miley and Liam never did make it down the aisle.

Hugh Grant
One of the most infamous cheating scandals of the 90s happened when Hugh Grant pleaded no contest to misdemeanour lewd conduct after being caught with his pants down -- literally -- with Hollywood prostitute Divine Brown. Although girlfriend Elizabeth Hurley stayed by his side, the couple eventually split in 2000. When the news broke, Grant owned up to his one-night stand and told Larry King, "I don't have excuses."

David Letterman

The Late Show got way more exciting in 2009 when Letterman went on-air to apologize for sleeping with multiple women on his staff and cheating on longtime love Regina Lasko, the mother of his young son. Although the two weren't married at the time of his affair with assistant Stephanie Birkitt -- they wed six months prior to the scandal breaking -- Letterman was still deeply remorseful to Regina for his actions. The truth came out after former CBS employee Joe Halderman attempted to blackmail and extort $2 million from Letterman to keep quiet about his affairs. Halderman pleaded guilty for attempted grand larceny and spent several months in prison. Letterman and Lasko stayed together and David says he's still working on the marriage

Rob Kardashian
Back in 2009, reality star Rob Kardashian and Adrienne Bailon ended their relationship after two years. It wasn't until he came clean on Keeping Up With the Kardashians that his infidelity was confirmed. Bailon revealed on her talk show The Real last year that she wrote a fake letter from a fake boyfriend to get Rob to leave her alone. "What all ya'll thought was that it was written by my boyfriend. It was not written by a boyfriend. That was written by me and my girl sitting on the sofa one day deciding to ourselves, 'Well, how can we make him stop calling me?'"

Chris Brown
As if Chris Brown and Rihanna weren't the most annoying couple in the world, Chris Brown admitted to his infidelity in 2013. In an interview with Power 105.1, he confessed, "I already had two girls at one point. It was honest. I'm at that point [of being faithful]." In the same interview, he said that he would not be okay if Rihanna had another partner, unless it was a girl. What a classy couple.

Billy Bob Thornton
Angelina Jolie must have a thing for men with girlfriends. In 1999, Billy Bob Thornton was living with girlfriend Laura Dern when he starred in the movie Pushing Tin with Angelina. Laura was away on a shoot at the time Billy and Angelina got together, and she later told the press, "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.

Keith Urban
At the end of 2006, 23-year-old model Amanda Wyatt claimed she had an affair with Keith Urban throughout the beginning of his relationship with current wife, Nicole Kidman. She told Daily Mail, "He used to call me and tell me how much he missed me making him laugh. Whenever he came home to Nashville, we'd get together. I never pressured him to commit." Even after the allegations, Nicole stayed by her boyfriend's side and the couple has since wed and welcomed two daughters.
