Mark Wahlberg and Justin Bieber have let it slip that they're working on a movie together, and Mark was very complimentary about his future co-star!

Mark said, "[Justin] is a very good athlete. He can play. But I also really think he can act. We're just going to have to make him realise that he's playing a character so he can't have the same hairdo!"

About the film, he revealed, "It's set in street hustling basketball". Previously, Justin also let slip, "We've been working on the script for a long time now!" Bring on the movie!
