— -- The latest cast member for Season 21 of "Dancing With the Stars" was just announced -- and it's a biggie!

"We're not playing games with your heart - @NickCarter is on this season of #dwts!" the show's official Twitter handle tweeted out this morning.

Carter, 35, tweeted right back and posted a montage of himself dancing back in his Backstreet Boys days.

"You ain't seen nothing yet," he wrote.

Carter spoke to US Weekly, who broke the news, and said N Sync's Joey Fatone inspired him to join the show.

"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 told the magazine.

Carter joins Bindi Irwin and American Pharoah Jockey Victor Espinoza on the cast, both were announced earlier this week.
