Serge Lifar
Diaghilev's life and the Ballets Russes were inextricably entwined. His most famous lover was Nijinsky. However, according to Serge Lifar, of all Diaghilev's lovers, only Léonide Massine, who replaced Nijinsky, provided him with "so many moments of happiness or anguish". Diaghilev's other lovers included Anton Dolin, Serge Lifar and his secretary and librettist Boris Kochno.
