Justin Bieber for ProactivJustin Bieber seems larger than life, but in truth he's just like any other teen: He gets zits.

The teen sensation has signed on as the latest pitchman for Proactiv. Bieber joins the ranks of Katy Perry, Avril Lavigne, Vanessa Williams, Jenna Fischer, and Julianne Hough as the face of the acne-treatment system.

"I'm definitely someone who suffers from acne," Bieber says on Proactiv's site. "I'm a teenage boy! So I use Proactiv so my face doesn't get like that. Proactiv is a great thing!"
