Zac recently finished work on his movie We Are Your Friends and now director Max Joseph has confirmed he will be shirtless often in it.

“There are maybe three times he’s shirtless,” Max told E! News. “He’s shirtless and you get a good dose of it. It’s not a flash but it’s not like he’s playing water polo for like six minutes or anything like that.”
