18. Katie and Carley

Bridezilla Katie battles with her family for top billing when her sister Stephanie calls her out in front of the entire bachelorette party, and her parents bicker at the rehearsal. But nothing compares to the meltdown Katie has when no one is around the night before the big day. Meanwhile, Bridezilla Carley is on a candy-only starvation diet, so she kicks her groom out of the house at the sight of his fast food. Carley also refuses to allow her groom to play his favorite music at the reception, imposes an age limit for his father's dates, and micromanages everything about her sister down to her deodorant!
