Newly single, Ryan Phillippe was definitely in a party mode at Teddy’s inside the Hollywood Roosevelt Hotel, where he mingled with several female clubgoers. Sporting a tight gray T-shirt, the actor hopped on the dancefloor and started getting down with somebody while Samantha Ronson spun tunes from the deejay booth. The actor and his lady friend were flirting, but then Phillippe started focusing his attention on a brunette. The two talked closely, getting pretty hands-on with each other as they danced. At one point Phillippe, who had a vodka drink in his hands all night, made a lap into the hotel’s lobby, where he chatted up a few more girls before returning to the club.
