KATY PERRY COVERS RIHANNA &... WILLOW SMITH! LIVE!

Katy Perry is on her California Dreams Tour and it looks like she's slipped in a couple of covers. Here's Perry, sounding damn good by the way, covering her friend Rihanna's Only Girl (In The World) (wishing her a happy birthday) and Willow Smith's Whip My Hair (with kitschy, fake flute playing...hilarious!). Katy, of course, has had enough hits of her own, but it's fun to see her covering other artists in such a cute way, acoustic and all.. Enjoy Katy's little set. I kinda wanna see this tour now!
