The actor jokes around about style secrets behind-the-scenes.

Thought Spanx were just for the ladies? Think again.

With the release of Tom Hanks’ latest film Larry Crowne around the corner, the actor joined co-star Julia Roberts for a sit-down with Access Hollywood’s Billy Bush. The interview took an unexpected turn when Bush haphazardly mentioned a scene in which Hanks appears in all his “tighty-whitey” glory.

“Oh, you had to go there,” Hanks groans before unleashing his fondness for a certain undergarment.

“As long as there have been tighty-whiteys, there have been Man Spanx. They do something for you down there,” he gushes. “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.”

“Girl, I love you in a pair of panties” Roberts chimes in.

You can see Hanks’ Man Spanx for yourself when Larry Crowne hits theaters on July 1^st.
