Nick Carter will compete on the next series of 'Dancing With the Stars'

He wrote: "You ain't seen nothing yet. #DWTS @DancingABC #NickCarterDWTS (sic)"

He later confirmed to US Weekly magazine that he is "excited" to get started and that he has his former rival and friend, 'N Sync's Joey Fatone - who competed on seasons four and 15 - to thank for persuading him to sign up.

Nick said: "I'm excited. [Joey] 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. 'You'll get what you put into it.' And I'm a hard worker, so I think it'll be fun."

However, it wasn't just Joey who made up his mind, younger brother Aaron Cater came fifth place in season nine and Nick, 35, admitted he has a lot of "competitiveness" towards his sibling and wants try and beat him.

He said "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, 'OK, I'm going to go there and represent the Carter name and do even better than what he did!' "

However, the 'Everybody' hitmaker will have his work cut out as he doesn't think he is a "great dancer"

He added: "I never considered myself a great dancer. Even though funny enough I've danced my entire life, I might have had a little insecurity on that end. But I felt this time around I had some time and I think it'll be a cool experience. I think they can teach me some stuff.

"I hope maybe I can become a better dancer! It'll be a great experience to learn how to ballroom dance."

Nick joins previously-announced contestants Bindi Irwin and Victor Espinoza in taking part, with the rest of the line-up due to be announced in the coming weeks.

'Dancing With the Stars' starts on Monday September 14 on ABC.
