Hell hath no fury like an angry bridezilla scorned!

When WeTV's Bridezillas premieres Sunday at 9 p.m. (EST), viewers will get a taste of one of the show's wildest brides-to-be yet.

In a sneak preview clip, bridezilla Krystal has a fit when her rowdy bridal party prepare to board a trolley as part of her wedding celebration. "Here's the deal: Don't use f--king vulgar language on the trolley," she snipes. "I swear to God, I will kill you!"
