When you break up someone's marriage (in this case, Reese Witherspoon's), you really can't be surprised when your boyfriend eventually starts cheating on you. From the National Enquirer:

Ryan Phillippe was a Voyeur nightclub on Feb 4. -- WITHOUT girlfriend Abbie Cornish. And he definitely was not on his best behavior! The "Crash" actor hung out in the smoking section, chatting with a gorgeous brunette in a red dress. He even got her number. (Print Edition - 2/22)

Oh what a shock:

It's over between actress Abbie Cornish and boyfriend Ryan Phillippe, her spokesperson confirms to People exclusively.

"Abbie ended the relationship with Ryan and she moved out of their home," the rep tells People. On Sunday, the actress was spotted removing her belongings from the house she shared with Phillippe while he was running errands and toy shopping with children Ava and Deacon.

Abbie has only herself to blame for this entire situation. When she decided to date an actor more famous for cheating on his wife than for his on-screen accomplishments, she should have known he wouldn't be faithful. If Abbie wants to make sure she's never betrayed by another man, she should just do what Katie Holmes did -- marry a guy that's repulsed by other women.
