Justin's movie career is over!

It's official: Justin Bieber will make his debut in a movie with Mark Wahlberg! Rumors swirled about the movie being canceled, but that's not true at all. Mark says the movie is happening and that Justin's an awesome actor! "He can act. I believe in him," Mark spills. Sources tell us the movie will be about basketball. We also hear Justin might (gasp!) cut his hair for the role. We can't wait to see this flick!
