R. Kelly Joins Lady Gaga, American Music Awards Line Up

R. Kelly and Lady Gaga will join forces for the first time on stage at the 2013 American Music Awards next week.

Lady Gaga broke the news during an interview with Music Choice Tuesday, saying "R. Kelly will be there — oh, I'm not supposed to say that… Oh, I said it anyway. Oh well. Sorry Robert!"

"We're gonna perform 'Do What U Want With My Body,' and we have a great chemistry when we perform together," Gaga went on to say in video below. "And he's so amazing, and I'm just looking forward to hitting the stage again."

"Do What U Want" is the second single lifted from her new album, "ARTPOP," which is expected to top the Billboard 200 next week.
