Channing Tatum "ate like a rabbit" before stripping off for his role in Magic Mike.
The Hollywood hunk stars alongside Matthew McConaughey and Matt Bomer in the movie, which follows a group of male exotic dancers.
Director Steven Soderbergh has revealed how the buff cast prepared to show off their bodies in the revealing roles.
"I can tell you that this cast was so disciplined. They ate like rabbits. It was lettuce with lemon juice on it," he told Collider.com. "Honestly, I've worked on movies with a lot of women who look great and take care of themselves, but I've never seen this kind of diligence. Maybe it was just fear.
"But, I didn't sense any competition because the fear of doing it bonded them really quickly."
The cast are seen in thongs throughout the comedy movie, which have set female pulses racing around the world. Steven has joked about how he chose the skimpy underwear.
"As you can imagine, it was a very personal process. I know what I like, so it didn't take long, at all," he explained.
"When you go in the thong shop, you do have to make decisions about which ones you're going to pick, but it's pretty easy to eliminate 99 per cent of what's hanging on these racks 'cause they're just silly or ugly. I think we were trying to find this balance."
