Dr. Rubin

Dr. Rubin is the principal of West Eastman High School in the second CGI/live-action film Alvin and the Chipmunks: The Squeakquel. She is an ecstatic Chipmunks fan and persuades them to perform in a music competition to save the school's music department. After she and the student body hear The Chipettes sing, she is pressured by them and Ian Hawke to allow a sing-off between the two groups. She becomes very emotional when The Chipmunks lose the chance to represent the school. She is also present at the concert at the end of the film and dances on stage with the public. Alvin didn't believe she was a fan until she showed The Chipmunks a tattoo of them on her bicep. She states that she got it at their concert in Denver on her birthday.
