VIDEO : Heidi Montag's Mom Apologizes for Selling Her Out

Lifetime's The Mother/Daughter Experiment: Celebrity Edition is going to have just as much screaming and crying as you'd expect from a show featuring reality star mother/daughter pairs attempting to repair their relationships.
You can see one of the tearful family therapy sessions in E! News' exclusive sneak peek at the premiere episode, in which The Hills star Heidi Montag and her mother, Darlene Egelhoff open up to each other about the biggest rift in their relationship: the fact that Egelhoff spoke out publicly against Montag's extensive plastic surgery.
