Vinny Guadagnino is convinced that his Jersey Shore castmate JWoww will be "a bridezilla".

JWoww's fiance Roger Mathews popped the question during a skydiving session while filming the Jersey Shore spin-off Snooki & JWoww.

The cast is notorious for getting into bar brawls and Vinny portends that a fight may go down on the couple's wedding day.

"[JWoww will be] a bridezilla," he joked to Us Weekly.

"She's going to fist fight Roger the day of the wedding!"

There is absolutely no way Vinny will miss JWoww's nuptial ceremony.

He supports his friend in all that she does.

"I have to [go]. We're like a family," he gushed. "I'm very excited."

Vinny is elated that JWoww and Roger decided to take their relationship to the next level.

He hopes that the pair don't suffer from pre-wedding jitters.

"I'm glad that it finally solidified," he said. "Hopefully they go through with it."
