Justin Bieber directed his first Proactiv commercial and has had fun with it.

Bieber disguised his voice as he spoke into a megaphone giving ridiculous instructions to the confused girls. He could barely contain his laughter after watching them execute his silly instructions.

When Bieber finally revealed himself, the girls were absolutely stunned and so starstruck that when asked if he was a good director, all they could manage was a huge grin and a faint “Yes.”

Check out the hilarious video below to see how Bieber pranked the girls!

If I got pranked by Justin Bieber I would be ROFL-ing! What would you do if you were one of the girls?
