When the Jersey Shore cast first arrived in Florence, Italy, Mike "The Situation" Sorrentino bragged to Ronnie Ortiz-Magro that he "kind of had sex" recently with Nicole "Snooki" Polizzi.
The only problem? She says it didn't happen.
After Ortiz-Magro, 25, shared Sorrentino's secret with Jenni "JWoww" Farley and on-again girlfriend Sammi "Sweetheart" Giancola during Thursday's episode, Farley, 25, asked Polizzi if the rumors were true.
"Mike is a big fat liar," Polizzi said in a confessional. "I have never hooked up with him."
Currently dating Jionni LaValle, Polizzi confronted Sorrentino, 29, about the alleged hookup. "You're telling everyone that I cheated on Jionni with you. I don't like you, I don't want to be friends with you, and I can't even look at you right now."
Though Sorrentino stuck by his story, claiming the truth would come out eventually, Polizzi, 23, insisted she turned him down when he tried to hook up with her.
"You're psycho!" she told him. "You have no friends in the house. I f–king hate you!"
