Rihanna "Sings" Redemption Song on Oprah

Rihanna butchered Bob Marley's "Redemption Song" on the Oprah show yesterday, but she did look hot while doing it. I'll give her that.

Does Rihanna have a vocal coach? This chick spends more time sending nude pics and shopping than she does working on whatever it is she tries to do when she gets on stage. She'd make a hot stripper, but the singing needs some work.
