Credit: Michael Rozman/Warner Bros. first broke the news that Dear John star Channing Tatum worked as a stripper when he was 18. And on Wednesday's Ellen DeGeneres Show, the actor, now 29, proves that he still has the moves.

See Us' exclusive video of Channing Tatum stripping!

"I was a stripper," he admits on the show. "Look, I'm not proud of it, but I'm not ashamed of it."

In 1999, Tatum -- who performed as "Chan Crawford" -- worked in a Chippendales-style revue called Male Encounter at a now-defunct Florida nightclub.

Tatum (who's wed to dancer Jenna Dewan) tells DeGeneres that as a male stripper he did "little shows."

He then gets up and dances in front of her.

"Now I'm embarrassed!" he admits.

DeGeneres says she wishes she had a dollar to tip him.

"Don't worry," Tatum tells her, "that one was on the house."
