So much for being "guidette" princesses.

Jersey Shore star Jenni "JWoww" Farley, 23, admitted on Fox's Strategy Room Tuesday that she and Nicole "Snooki" Polizzi aren't even Italian!

J-Woww says she's Spanish and Irish, while Snooki, 21, is Chilean.

The MTV reality show was slammed by Italian-American groups for perpetuating "negative stereotypes," UNICO National President Andre DiMino told Fox last year.

"If you replace Italian-Americans with any other ethnic group, would they use such a pejorative term to promote the show?" he fumed.

JWoww also shattered another Jersey Shore myth: The girls don't believe in GTL! (Which stands for gym, tan, laundry, the schedule made famous by co-star Mike "The Situation" Sorrentino.)
