The stars of “Jersey Shore” are still earning a fortune in appearance fees. Mike “The Situation” Sorrentino and Nicole “Snooki” Polizzi are the top earners, at about $15,000 for a regular club or event appearance. Jenni JWoww” Farley, Paul “Pauly D” DelVecchio and Vinny Guadagnino get about $12,000. Warring lovers Sammi “Sweetheart” Giancola and Ronnie Magro command about $8,000, while new cast member Deena Nicole Cortese trails with $5,000. Still, it’s not bad for a few hours work. A source said, “MTV still limits their paid personal appearances to one a week, but they are doing all they can to cash in while the show is still hot.”
