Justin Bieber Pranks Proactiv Customers

Justin Bieber is one of the famous faces of Proactiv and they let him step into the director’s chair for a new commercial.

In the spot, some girls come into the studio to shoot some product spots for the brand. Justin then gets on the bullhorn from a hidden area pretending to be the director. He tries to disguise his voice and then orders the girls to strike poses, etc.

Justin has a hard time keeping a straight face, which makes us wonder if he’ll be able to when he appears on Punk’d later this year.

Eventually Justin reveals himself and naturally, the girls go nuts.

Check out the spot below! What would you do if you got pranked by Justin?
