Heidi Montag and Spencer Pratt‘s fake drama-filled wedding is coming and in true Spiedi fashion they made sure their rehearsal dinner was just as bad. They were celebrating at the Beverly Hills spot Cut last night when something happened.

“”Heidi’s sister Holly got into a huge fight with Spencer. She was crying in the bathroom and moaning about how he was disrespecting her,” the insider tells Life & Style. “The next thing you know, she and Spencer are going at it in the front lobby of the restaurant. He was calling her immature and rude and she was crying. It was pretty bad.” Of course, the insider adds, the cameras were rolling, “but Holly still seemed genuinely upset.”

It seems like that family always fights, it’s in their blood. The drama made Heidi stressed and she only drank water. There was over two dozen people at the three hour dinner. It sounds like they are really taking this serious and spending all of MTV‘s money.

The night ended with Heidi and Spencer sharing a slow dance in the lobby of the Beverly Wilshire hotel. I am sure this is nothing compared to what’s in store for the wedding.
