In 1921, Diaghilev staged a lavish production of The Sleeping Beauty in which Lopokova danced the Lilac Fairy and Princess Aurora. The production was a flop, but it brought her to the attention of John Maynard Keynes. He "sat every night in the stalls, enchanted by Lydia as the Lilac Fairy casting spells over the cradle." The two soon became lovers, and they were married in 1925, once her divorce from Barrocchi had been obtained. Until now, Keynes's closest relationships had been with the members of the Bloomsbury group, especially Vanessa Bell and Duncan Grant, who had been the great love of his life. They and other members of the group, such as Virginia Woolf and Lytton Strachey, found Lydia difficult to accept and were resistant to her partnership with Keynes for many years even after their marriage took place. (Some of them later regretted their snobbery; E.M. Forster, for Example, wrote: "How we all used to underestimate her.") However, she maintained friendships with many other members of London's cultural elite of the time, including T. S. Eliot and H.G. Wells. During these years she became a friend of Picasso, who drew her many times. Lopokova is represented as Terpsichore, the muse of dancing, in The Awakening of the Muses, a mosaic at the National Gallery, London, laid by Boris Anrep in 1933. Also in 1933 she danced her last ballet role, as Swanilda in Coppélia, for the new Vic-Wells Ballet.
