If Justin Bieber is in Zoolander 2 it has a legitimate chance to ruin the movie, and that’ saying a lot because I can’t imagine the movie is going to great to begin with. Being great isn’t the point of the movie, though, it’s just a chance to spend some time with some wacky pals from the past. Justin Bieber being in this movie for even a second ruins that time. Bieber has to understand that he’s popular with little girls and that’s it. Don’t try and get into the adult world and into our beloved comedies. Go hang out with your 10 year old fans and leave the big boy stuff to everyone else.
