Ryan Phillippe: Hitting on Rihanna?

They’ve only been dating for three months, and already it looks like things aren’t going too well for Ryan Phillippe and Amanda Seyfried.

The “Cruel Intentions” stud, who was seen hitting up a West Hollywood Starbucks store yesterday, and the “Big Love” babe may be on the outs.

Ryan was seen trying to pick up Rihanna at the Gucci/Roc Nation event on February 12th, though it seems he was unsuccessful.

An observer told press, "He said something to the effect of, 'What are you doing tonight?' and she signaled 'sleep.’ She was trying to be polite, but she was genuinely not interested. When a couple of her friends came up to join the conversation, he just walked away."

Furthermore, an insider shared that Ryan and Amanda are keeping things light and fun. "It's casual. They'e friends who hang out romantically from time to time and that's it. At one point, there was a chance it would develop into something more serious, but it never did. There's no commitment."
