This just in:
Not all famous people are loyal.
Some cheat. Many cheat, in fact.
And, in turn, the people with whom they cheat become famous themselves.
Below, for example, is a rundown of well-known men and women who allegedly slept with celebrities while those celebrities were in relationships...
Sara Leal was the 22-year old who told Us Weekly all about the time Ashton Kutcher had sex with her in a hot tub...while he was still wed to Demi Moore.
She sort of outed herself as Jay Z's mistress after Beyonce released an album titled "Lemonade" that clearly accuse her husband of cheating. (We said Rachel Roy, people. Not celebrity chef Rachael Ray.)
Patient zero of the Tiger Woods scandal. She later went on to serve as David Boreanaz's side-piece.
London's dalliance with Hank Baskett is still stirring up drama. We hope for her sake that she's working on scoring a reality show deal.
Cady Groves was a little-known singer songwriter...until she (allegedly) broke up the biggest marriage in country music. We don't know if Cady is any good when it comes to writing country songs, but she sure knows how to live one!
Photos of Chloe canoodling with Scott Disick led to the reality star getting dumped by Kourtney Kardashian. She still says the pics were misleading, and nothing happened between them.
