Granddaughter of Sally Marr and daughter of comedian Lenny Bruce, Kitty made her film debut as a plump teenager in the girl-gang film The Jezebels aka Les loubardes (1975), directed by 'Jack Hill (I)', playing well the role of a buxom yet frail-character girl who would do anything to be accepted by the tough gang leaders. She subsequently followed a career as a pop singer, opening for acts such as 'George Carlin' and Diana Ross.
