He’s not the only one. Sanders’s wife of seven years, Liberty Ross, was “devastated,” a source tells PEOPLE of the model-turned-actress, who played Stewart’s mother in the hit film. “They seemed like a perfectly happy family,” the source says of Ross and Sanders, who have two children. “This was devastating for her.” Though Sanders, 44, was recently spotted out wearing his wedding ring, that is no indication that Ross has forgiven her husband.
