Question: How many years had the Ballet Russe de Monte Carlo been doing performances the year that Rudenko signed up with them? Passage:In 1938 Rudenko was signed up to the Ballet Russe de Monte Carlo, where, at 17, she was their youngest soloist. Her stage name was Lubov Roudenko, and she was also popularly known as "Spitfire Lu-Lu." She had a can-can sequence in the 1938 ballet Gaîté Parisienne choreographed specially for her by Léonide Massine. She would later reprise this role in the 1941 Oscar-nominated short film The Gay Parisian. Whilst with the Ballet Russes, Rudenko was the subject of several drawings by Henri Matisse in 1939. Four of his portrait sketches of her are now in the Fogg Museum. Matisse also made a drawing of Rudenko in the ballet  Rouge et Noir. While on tour with the Ballet Russe, Rudenko performed the role of the Cowgirl in the 1942 ballet Rodeo until the tour reached New York and Agnes de Mille, the original choreographer, reclaimed the role for herself. Disappointed by this, Rudenko quit the Ballet Russes, and took a better-paid job performing in a Broadway production of The Merry Widow. This production launched at the Majestic Theatre on 4 August 1943, with Rudenko and James Starbuck leading the character dances, including a comic polka and a can-can number. After this, Rudenko played Grisette in Nellie Bly, a short-lived 1946 musical based on the life of Nellie Bly, and then became lead dancer for the 1946-49 Broadway production of Annie Get Your Gun, but following a knee injury, decided to pursue a career in fashion design. She continued performing until 1951, appearing in the 1950-51 Olsen and Johnson revue Pardon our French.
