The Chipettes are a fictional group of three female anthropomorphic chipmunk singers—Brittany, Jeanette, and Eleanor—first appearing on the cartoon series Alvin and the Chipmunks in 1983. In this and related materials, the Chipettes served as female featured characters in their own right, starring in numerous episodes. The title of the show was changed from Alvin and the Chipmunks to simply The Chipmunks in 1988 to reflect this. In the cartoon series and the accompanying feature films, all three of the Chipettes were voiced by their creator, Janice Karman, the wife of Ross Bagdasarian, Jr. (son of Ross Bagdasarian, Sr., the creator of The Chipmunks). Karman also wrote and voiced the Chipettes' dialogue on their studio albums, while studio singers such as Susan Boyd, Shelby Daniel, and Katherine Coon provided their singing voices. In ALVINNN!!! and the Chipmunks, Eleanor is voiced by Vanessa Chambers, the daughter of Ross Bagdasarian, Jr. and Janice Karman. The first character designs for the Chipettes were drafted by Corny Cole for their 1983 debut. These were later revamped by Sandra Berez for The Chipmunk Adventure and the later seasons of the show.
