Ryan a Cheater?

As reported yesterday on daGspotblog.com, Ryan Phillippe and Reese Witherspoon are splitsville. But is Australian actress Abbie Cornish the other woman? Evidently, Cornish and Phillippe recently filmed the movie 'Stop Loss' together in Austin, Texas and that's where all the rumors have started.

I don't know if its true but I hope its not. On the other hand, if its not we're all dragging this poor chick thru the mud and labeling her a homewrecker. So in that case, I hope its true??? I dunno this whole gossip thing still confuses me.
