Yes, This is J-Woww of 'Jersey Shore' as a 5th GraderJWoww on 'Jersey Shore' is the master of being sexy and tough, of partying through the night ... but that wasn't always the case.

"She wasn't very popular," a grade school classmate of Jenni "J-Woww" Farley tells RadarOnline.com. "Jenni didn't have a boyfriend that I remember and she wasn't on any sports teams or in any clubs really."

Radar now has a charming batch of photos from J-Woww's youth, ranging from her elementary school days to her time at Columbia High School in East Green Bush, New York.

"She was quiet, but nice to other people," the classmate says. "She had a close best friend and she mostly hung out with her."

Though J-Woww rocks her Filthy Couture lingerie line these days, the former peer says Farley was a low-key dresser back in the day. "She always wore jeans and hoodies, she didn't really dress up."
