Rihanna shows 'American Idol' finalists how it's done

Rihanna is on "American Idol," singing "California King Bed." She's captivating, owns the stage; you can't take your eyes off her or stop listening.

What a great, distinctive voice, smooth as chocolate. Passion and pain are both in there. 

Big applause for her at the end, and she's giving us that goofy smile. Ryan Seacrest gets her to talk about some VIP section they're building on stage for her tour, where fans can get up close.

She makes it seem like something revolutionary, it's just stage seating, yo.
