Rihanna performs "California King Bed" live on American Idol

Rihanna performed her new single, "California King Bed" live on American Idol last night.  In this performance Ri Ri performed the song by herself for the first time, not to long ago she sung it with Jennifer Nettles from Sugarland at the ACMs.

I think Rihanna did a great job.  Their are a lot of people that say Rihanna can't sing, I believe she can.  I will be honest, sometimes when she performs she doesn't sound her best, but last night was flawless.  Whatever she did to prepare for this performance she needs to bring to her others.

Check out the performance below.
