Yeah, once your man starts macking on other ladies, it's time to call it quits.
Following reports that Ryan Phillippe was all over Rihanna the other night, sources have confirmed that Ryan is no longer involved with Amanda Seyfried. According to an insider, the pair have broken up officially, claiming that their "chance" to develop something "more serious" is over.
Still, another source close to the duo says that neither Amanda or Ryan think that moving on will be hard to do. In truth, neither of them really consider the split to be a "big deal."
Well, good then. We thought you guys were cute together, but you're both still so young. Plenty of other potential hotties to hit up in Hollywood.
