(Cover) - EN Star Style - Tom Hanks has revealed he has been wearing Man Spanx'.

The actor, who is starring alongside Julia Roberts in his latest movie Larry Crowne, has talked about his pant-less scene in the comedy.

Reducing his co-star to tears of laughter, the 54-year-old star revealed how the constrictive undergarment shaped his form.

"Oh, you had to go there!" he moaned when asked about his appearance in small white briefs by Access Hollywood. "Let me tell you: As long as there have been tighty whities', there have been Man Spanx."

Tom says the undergarment did wonders for his butt. The Hollywood star says despite feeling a little uncomfortable, they helped him achieve a perfect look.

"They do something for you down there. They just bring them together a little, so that little peach forms. You don't even need to see the cleavage, just get a sense of the strong, vice-like grip that you can get down there sometimes," before co-star Julia quipped "Now that is suffering for your art."
