Channing Tatum's Secret Stripper Past

Usmagazine.com shares a video of Channing Tatum, 29, dancing in a revue called Male Encounter in 1999.

Then 18, the star -- who performed under the alias "Chan Crawford" -- approached owner London Steele about a job.

"He was shy at first, but he really knew how to work the stage," Steele tells Us, adding that Tatum lip-synched in the act and earned $50 a night (plus tips) during his year-long stint.

"The women went crazy for him!" Steele added.

The revue had a strict no-nudity policy.
