Jenni ‘JWoww’ Farley ‘Cuts’ Up at GNC (PHOTOS)

Mike “The Situation” Sorrentino had better watch out; he has some competition for the title of Jersey Shore’s resident abs expert.

Sorrentino’s castmate, Jenni “JWoww” Farley, dropped by the GNC store in New York’s Manhattan Mall on Wednesday to promote the fat-burning product Ab Cuts—and rocked some pretty fantatic purple bling while she was at it.

Hit up the photo gallery to see JWoww work the promo circuit. (And in case you missed the ultra-awesome trailer for the upcoming third season of Jersey Shore, check it out here.)
