Mary-Kate Gets It On With Gandhi in a Phone Booth

You heard it here first: Oscar-winner Sir Ben Kingsley is now taking acting advice from one of the Olsen twins.

In the summer indie flick The Wackness, Mary-Kate Olsen plays a hippie stoner who takes a psychiatrist (Kingsley) into a phone booth for a quickie. But what happens next is the real shocker...

Kingsley admits that he turned to his young costar for counsel. "I asked her, 'You're the boss. You guide the choreography of this scene, because your character needs to tell a story,'" he told E! News this week. "'You have to guide me.'"

The scene lasts only a few seconds in the film, but according to the film's star Josh Peck, Mary-Kate became a real Sir Ben groupie behind the scenes. OK, hot-chocolate-drinking buddy, at least.

"[Ben's] just about as pimp as it gets," Peck tell us. "So he's infectious when it comes to women, I think."

Obviously, because he knows the golden rule: When it comes to phone-booth sex, let her lead.
