LOL! TREY SONGZ WENT TO BEAUTY SCHOOL!

Trey Songz went to beauty school, where he learned to wax, pluck and otherwise beautify the opposite sex? Well, now you do, because during the premiere episode of MTV's celeb-secret-revealing new show "When I Was 17" (airing Saturdays at 11 a.m.), these three stars proudly dish on outrageous stories from their pasts.

Songz laughed about how he enrolled in a program to obtain a barber's license because he thought he'd get out of class early. Only problem was that he was then stuck cutting, moussing and Jheri curling for hours.

"I actually used to arch my girlfriend's eyebrows," he laughed. "Don't judge me! But it got me 'cool' points!"

Come prom season, he also hooked his friends up with free cuts. But things didn't always work out so well. "My clippers got so hot, I remember I messed my homeboy's head up so bad," he recalled, smiling. "He had scars for, like, the next two days. All that. My bad."
