Glee star Lea Michele was left speechless on the set of new movie New Year's Eve when her co-star Ashton Kutcher stripped off for a saucy prank.
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, "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."
