Rihanna took to the American Music Awards stage to perform her new single "Rehab":

That bedazzled eye patch was killing me. The gimmicks must stop for everyone in the industry. Gloves, shades, chains, now
Mama Tina's special creole creations eyepatch? No ma'am. The performance was blah per usual but Rih also looked fabulous per usual. I'm sure that makes up for the lack of skills to some people.
Elvis Kanye performed "Heartless" on the AMA stage. That animal hanging out his back pocket kept distracting me. Cool performance though.

And
Alicia Keys performed "Superwoman" bringing out surprises like
Queen Latifah to rap and sing on the track as well as Opera extraordinaire
Kathleen Battle. I loved it.
