Sparks flew on Jersey Shore Thursday, along with some well aimed pickles, as Nicole “Snooki” Polizzi and Mike "The Situation" Sorrentino finally had their knock down drag out nasty fight about their alleged “hookup!”

In the latest installment of the group’s over-the-top MTV reality show, the showdown between Snooki and The Situation finally happened.

Talking to her boyfriend (and now fiancé and baby daddy Jionni LaValle, Mike boasts to him that he hooked up with his girlfriend.

“I think you’re a good [expletive] kid,” The Sitch says.  “I can’t look you in the face and not let you know, as a man.”

Then he drops the bombshell on him. “I don’t know if you heard the rumors…I want to tell you as a man, we did hook up.”

Playing it cool, Jionni thanks him, shakes his hand and immediately tells Snooki, who is furious with her roommate.

When the two see each other next the fight begins with pre-pregnancy Snooki dropping the f-bomb first.
