Jenni "JWoww" Farley is no ordinary bride-to-be!

After recently confirming her engagement to Roger Mathews, 37, Farley's Jersey Shore costar, Vinny Guadagnino, 26, assured Us Weekly he'll be at their wedding. (The engaged couple has yet to set a date.)

"I have to. We're like a family," Guadagnino told Us Weekly at the NBA2K13 premiere at 40/40 Club in New York City September 26. "I'm very excited."

Guadagnino added that he knew a proposal was in the works. "I'm glad that it finally solidified," he said. "Hopefully they go through with it."

The MTV reality star predicted Farley -- who famously punched Mike "The Situation" Sorrentino on Jersey Shore -- will be "a bridezilla" as she preps for the milestone event. "She's going to fist fight Roger the day of the wedding!"

Like costar and BFF Nicole "Snooki" Polizzi, 24, Farley met her boyfriend while filming Jersey Shore in Seaside Heights, New Jersey. (New parents Polizzi and fiance Jionni LaValle, 24, are planning to wed in 2013.)

"Our men would still be doing what they're doing now if it wasn't for us," Farley told Us earlier this year. "They're not dating us for JWoww and and Snooki -- they're dating us for Jenni and Nicole."
