Anita Pallenberg, an actress and model who starred opposite Mick Jagger in Performance and had three children with his Rolling Stones bandmate, Keith Richards, has died. She was 73. Pallenberg died Tuesday, her friend Stella Schnabel, the daughter of painter and filmmaker Julian Schnabel, announced on Instagram. No cause of death was revealed. In 1968, Pallenberg appeared as The Black Queen in Barbarella, starring Jane Fonda, and as Nurse Bollock with Marlon Brando and Richard Burton in Candy. She also filmed Performance that year, but Warner Bros. did not release the violent, hallucinogenic film until 1970.
