While filming a commercial for the acne treatment system, Proactiv, spokesman Justin Bieber took the opportunity to surprise (and prank!) a few fans. Real Proactiv users were invited to help film a new commercial and were told to do whatever the "director" behind the curtain told them to do. The "director" (aka Justin) instructed the girls to do ridiculous poses, spins, and more in front of the camera -- all while disguising his voice with British and Southern accents!
