Report: Rihanna and Ryan Phillippe Heat Things UpHot off the heels of her breakup with Matt Kemp, it looks like someone new is making Rihanna feel like she's the only girl in the world.

According to, the 'S&M' singer has been getting cozy with actor Ryan Phillippe, but is trying to keep things quiet for now.

Phillippe, who most recently dated Amanda Seyfried, has been dogged by breakup rumors recently, which Seyfried has adamantly denied, saying, "That Rihanna story is not true. That is so f**king not true!"

Despite Seyfried's reports to the contrary, a source says that following the Gucci/Roc Nation event on Feb. 12 where Rihanna and Phillippe were spotted flirting, "They totally had sex. And it wasn't even the first time!"
