Rihanna Performs "California King Bed" on Idol / by

Earlier tonight, Rihanna took to the stage on American Idol and performed "California King Bed". Check out the performance after the jump.

She did pretty dayum good! Her vocals are just getting better and better. I remember when I first heard the song on the album and I was thinking that I couldn't WAIT to see how she performed the song, and she pretty much did it exactly how I visioned...lovely.
