Bridezilla Alex hasn't invited her own sister to the wedding, but she has invited her to the bachelorette party. The sisters spend most of the evening screaming when Alex invites their brother's ex to the festivities, but that's nothing compared to the smackdown Alex has with her own mother... Meanwhile, Bridezilla Stephanie's destination wedding is causing her grief when her own groom tells her he will be several hours late to their rehearsal. Later, a distraught Stephanie loses her cathedral veil on her wedding day, and everyone is running late -- too late. Will this bride wind up at the altar all alone?
