From wiki--Nureyev was gay and died of AIDS

In 1961, when Fonteyn was considering retirement, Rudolf Nureyev defected from the Kirov Ballet while dancing in Paris. Fonteyn, though reluctant to partner with him because of their 19-year age difference, danced with him in his début with the Royal Ballet in Giselle on 21 February 1962. The duo immediately became an international sensation, each dancer pushing the other to their best performances. They were most noted for their classical performances in works such as Le Corsaire Pas de Deux, Les Sylphides, La Bayadère, Swan Lake, and Raymonda, in which Nureyev sometimes adapted choreographies specifically to showcase their talents. The pair premièred Ashton's Marguerite and Armand, which had been choreographed specifically for them, and were noted for their performance in the title roles of Sir Kenneth MacMillan's Romeo and Juliet. The following year, Fonteyn's husband was shot during an assassination attempt and became a quadriplegic, requiring constant care for the remainder of his life. In 1972, Fonteyn went into semi-retirement, although she continued to dance periodically until the end of the decade. In 1979, she was fêted by the Royal Ballet and officially pronounced the prima ballerina assoluta of the company. She retired to Panama, where she spent her time writing books, raising cattle, and caring for her husband. She died from ovarian cancer exactly 29 years after her premiere with Nureyev in Giselle.
