Justin Bieber Is Perfecting His Blue Steel For a Zoolander 2 Cameo

The cast of Zoolander 2 just got even larger. Ben Stiller posted a picture of himself opposite Justin Bieber this week, confirming that the pop star will be making a cameo in the comedy. I have to say, I'm really impressed with Bieber's Blue Steel! Then again, Bieber is actually a model. Aside from his stint on CSI: Crime Scene Investigation and some random cameo credits, he hasn't acted much. This could be the beginning of a whole new chapter for Bieber! Or it could just be a really quick appearance — à la Billy Zane. What do you think of the casting news?
