Actor Chris Pratt has revealed he moonlighted as an amateur stripper before breaking into acting.

The Zero Dark Thirty star admits he has always been comfortable with his body and decided he could make good money showing it off.

He tells, "I was always a very much naked person (sic). I loved to always get naked (sic).

"I was very free, so I thought, 'I may as well get paid'."

Pratt performed mostly at bachelorette parties, but once danced at a party for his friend's grandmother.

He continues, "It was a surprise. I don't know how it got around to them, but they paid me $40... I did go one time and audition on a stage for a club, but I don't think I got the job. I don't think I'm a very good dancer."

The father of one, who is married to actress Anna Faris, also explains he likes to keep his body in shape and doesn't enjoy gaining weight for movie roles.

He says, "By gaining a s**t ton of weight, I affected not only the way I looked, but also that rhythm.

"I felt terrible. I felt mentally dull. I felt that I wasn't fulfilling my duties as a husband in the bedroom. I felt no sexual desire. I felt really, legitimately depressed."

He isn't the only big name with a stripper past - Channing Tatum chronicled his past as the ultimate ladies man in the film Magic Mike.
