Ann L. Rothschild (born  March 1, 1902 – October 22, 1981) credits variously as Little Ann Little, Annabel Little and Ann Little Werner, was an American vaudevillian, voice actress and singer who gained fame in the 1930s as the voice of Betty Boop, taking over the voice from original portrayer Margie Hines. From 1931 to 1933, Little Ann Little made recordings for the "Betty Boop" cartoons and tour and appeared in variety shows throughout the country. 
Rothschild got the job as the voice of Betty Boop as the result of a contest held by Paramount Pictures for a girl with a squeaky voice. She was also well suited for the role physically, being only four-foot-ten and weighing 100 pounds.
Little went on the road with the Fleischer Studios artist Pauline Comanor. Ann would pose while Pauline drew her as Betty Boop. They both finished the act with a "boop-boop-a-doop."
Little had started in show business in 1925 as a member of the pony chorus with the Greenwich Village Follies. She was also an RKO discovery and at one time had her own program on the NBC network as singer Little Ann Little.
