On the first season of The Voice , Adam Levine and Christina Aguilera sang about having "Moves Like Jagger." But for the upcoming season, the two will be singing a song actually written by Jagger.

Entertainment Weekly reports that for the September 10 premiere of season three of the NBC reality show, Adam and Christina have teamed up for a "super-secret performance of a Rolling Stones song."  "Moves Like Jagger," of course, was a salute to the legendary stage presence of Stones frontman Mick Jagger.

Adam also tells EW that he and Christina are "no longer bickering" on the new season.  As for his coaching strategy, he tells the magazine he doesn't have one.  "You're not fortifying troops for battle," he explains. "You're singing. It should be fun." 

Meanwhile, Christina tells the TV show Extra that she's not worried about the pop diva face-off that's brewing as Mariah Carey takes a seat behind the judges' table on American Idol and Britney Spears gives her opinions on The X Factor . 

“You know I love that. All these artists are coming together from all the experience that we've had and we're being able to take that and feed this new wave of talent coming up,” Christina says.  "Britney's so talented. I mean, she's a pro. She's been at it for a number of years now. We did grow up together. It's actually cool that these strong women are joining the club and they're gonna have fun.”
