Backstreet's back... to the dance floor!

Nick Carter is joining the cast of season 21 of Dancing with the Stars, he reveals exclusively to Us Weekly. "I'm excited," he dished in the latest issue. Of all people, N'Sync boy bander Joey Fatone talked him into it!

"He talks about it all the time and I was really debating if I wanted to do it, and he said, 'It's a great experience, it keeps you in shape and it'll teach you a lot of stuff.' He said, 'You'll get what you put into it.' And I'm a hard worker, so I think it'll be fun," the blonde hunk explained.

He won't be the first one in the fam to take a stab at the Mirror Ball trophy!

"My brother was on it; he did great; and he's a great little dancer and entertainer so I saw it through his eyes throughout that experience. And there's a lot of competitiveness in me and I think there's a little something inside of me that says, 'Okay, I'm going to go there and represent the Carter name and do even better than what he did!'" he added.

We have a feeling he's going to rock DWTS!
