Zayn Malik's Got Nothing On Them! The Most Notorious 'Celebrity Cheaters'

When we heard that Zayn Malik had been accused of cheating on girlfriend of nine months Perrie Edwards last week with Aussie waitress Courtney Webb, we have to admit were devastated.

We thought the One Direction hunk was head over heels for the Little Mix babe but after scrapping ourselves off the floor, we realised he's not the first celeb to cheat. Yes that's right, it's hard to stay faithful when you're a young, hot star with groupies throwing themselves at you left, right and centre and while Zayn might be feeling bad about himself now he should remember he's not the first and he's certainly not the worse.

Take a look at the most notorious celebrity cheaters, who make Zayn almost look angelic in comparison.

Ashton Kutcher

Ashton and Demi: Split after six years and one cheating scandal (WENN)

Ashton and wife Demi Moore were one of the hottest couples in Hollywood until waitress Sara Leal claimed she'd slept with actor after a nude hot tub romp in September 2011. To make it worse, it was his sixth wedding anniversary with the 'Ghost' actress and he reportedly didn't use protection. Urgh.

Wayne Rooney

Next up is Wayne Rooney the Manchester United player allegedly paid £1,000-a-night prostitute Jenny Thompson for secret sex sessions while wife Coleen was pregnant with son Kai. The fling lasted seven months, with Wayne even taking her on nights out with his team mates. It wasn't the first time either – in 2002 he allegedly cheated on Coleen again with prostitutes – one of whom was a grandmother. Disgusting behaviour!

Jesse James

Sandra Bullock thought she'd found her Mr Right when she wed motorcycle builder and Monster Garage host in 2005. One of the most stable relationships in Hollywood, James was by Sandra's side as she collected her Best Actress Oscar in 2010 for 'The Blind Side' but weeks later the actress was devastated by allegations that Jesse had cheated on her with a string of women throughout their relationship.

They were separated by April that year. Jesse clearly didn't learn his lesson either, his ex-fiancé Kat Von Dee has since claimed he cheated on her with over 19 women. Shame on you JJ!

Kristen Stewart

Yes, the only girl to make it on our most notorious list, the 'Twilight' babe shocked everyone when she cheated on Robert Pattinson with married director Rupert Sanders. The couple came clean in July after Us Weekly published pictures of the pair kissing in Hollywood. What was really shocking about this betrayal was not just the millions of 'Twihards' around the world but that Kristen did it despite Rupert having two children and working with his wife on the film where they met 'Snow White And The Huntsman'. She was also wearing boyfriend Rob's clothes when she did the deed with Sanders – classy!

Tiger Woods

He was the king of the golf world, until it was revealed he was a sex addict who'd cheated on his wife Erin Nordegren. It started when Woods crashed his Cadillac Escalade SUV outside his Florida home, reportedly during an argument with his wife. Allegations with a string of women, with the National Enquirer, who broke the story in 2010, hit the headlines for weeks with sordid accounts of sex sessions with prostitutes and porn stars. He's been accused of sleeping with up to 121 women. Not only did wife Erin leave him, Woods lost sponsorship deals and took a break from his career as he got his personal life together. While he's now returned to the golf green he no longer dominates as he used to, so he lost his game on and off the course!

Jude Law

When Jude started dating Boho babe Sienna Miller everyone thought they were the perfect beautiful couple. That was until he became the ultimate cliché and allegedly seduced his children's nanny in July 2005, just seven months after becoming engaged to Miller on Christmas day. They tried again but ultimately broke up. Classy stuff Jude, classy!

Chris Brown

Some of you might have forgotten this cheating scandal when Rihanna found text messages from Brown's alleged other woman, because it was eclipsed by a whole different scandal, but according to insiders the argument which led to the singer assaulting in 2009 his then girlfriend was over his infidelity. The couple were on their way home from a pre-Grammy party when the 'Diamonds' singer reportedly confronted him over text messages from another woman. The pair argued and we all know what happened next. Rihanna's battered face was plastered all over the world, Chris got charged with assault – all because of another woman!
