In their new issue, US Weekly says that Ryan Phillippe and Amanda Seyfried are not serious. Apparently the two just call each other when they need sex. They say that Ryan hit on Rihanna last week but was shot down. Nice one. Always nice to see someone who thinks they are all that turned into something not all that. Later though he did leave the party with some other woman who was willing to be a one night stand. Well, everyone needs a sex buddy, but I am wondering if perhaps Amanda thought it would be more. She does seem to keep dating guys or being with guys who are players.
