Beyoncé bounced and Michael Jackson was on a mission to launch the new song "What More Can I Give?" inspired by September 11th. The King of Pop's weekend was wild. He treated crowds to autographs, handshakes, and hugs.

Back onstage, Beyoncé blew away the crowd with her sexy number. And our Ryan Seacrest and Radio Music Awards co-host Brooke Burns gave us a look around the Aladdin Hotel, as P. Diddy, Michelle Branch, and Jewel jammed.

Jewel says, "I love this town."

And once the show started, Seacrest couldn't help reliving his former romance with Burns, or giving Burn's new boyfriend, Bruce Willis, a hard time. He said, "You won't date a guy who actually has hair."

Willis didn't seem to mind, he's got the girl, and he gave her a smooch backstage.

Michelle Branch and Nelly won awards on the show, but when they got back to their rooms the stars found they had been ripped off. Nelly says he lost $1 million in jewelry, while Branch was missing computer equipment.

At least these award-winning artists didn't leave Vegas empty handed.
