The Chipettes first appeared on Alvin and the Chipmunks in the early 80s. Their names are Brittany, Jeanette and Eleanor.
"We're hoping that there are all sorts of new things going on; we loved doing this movie, and we love the new look of it," agreed Ross Bagdasarian, Jr., son of the legendary Chipmunk creator and producer on the movies. "We just want to take the chipmunks where no other chipmunk has ever gone before."
