Rihanna just moved from NY to LA, and while she loves to go bowling with her friends, she says she's terrible at it.

"I'm horrible [at bowling], but that's why I have fun doing it because I'm so bad," she says. "I get strikes, just not the right way."

Well, she doesn't have to be good at knocking down pins when she's knocking everyone out with her music. Rihanna recently performed in our Sessions studio and blew us away with her rock-influenced versions of 'SOS' and 'Umbrella.' See for yourself.
