The singer/actress has a role as Kutcher's onscreen love interest in Garry Marshall's upcoming film, which features a star-studded cast of actors including Robert De Niro, Michelle Pfeiffer, Jessica Biel, Jon Bon Jovi and Zac Efron.
Michele has revealed the actor enjoyed joking around on set, and one of his pranks involved surprising her without his clothes.
She tells Okmagazine.com, "He really takes everything so seriously, but then he would also make me laugh so hard and play pranks on me. One day, I opened up a door and he was supposed to be there fully clothed and he wasn't. That was awesome."
Sounds like quite the prank. It isn't the first time Ashton's bared all. He also did so for the promos for "Two & a Half Men" and the Ellen Degeneres Show.
