Brittany Miller is the lead singer and leader of the The Chipettes and is the female counterpart of Alvin. She is the older sister of Jeanette and Eleanor. Her last name is Miller in the 80's cartoon, but she does not have a stated last name in the CGI films. It is presumed to be Seville because of The Chipettes being adopted by Dave. However, this would be controversial, as it would make her Alvin's adopted sister rather than his love interest.
