The origins of the Chipettes can be traced to the 1982 Alvin and the Chipmunks album "The Chipmunks Go Hollywood" (RCA, 1981). On this album, Alvin sings a duet with a female character billed as Charlene the Chipette. Charlene is featured on the song "You're the One That I Want" from the soundtrack of the motion picture "Grease". Charlene was depicted on the album cover as having a long, golden blonde ponytail, and seems to have been the basis for the later character of Brittany.
