Though her basic concept is retained in the CGI films, there are some notable differences. Besides appearance, her personality is toned down. She is a lot friendlier and polite, making it easier for others to approach her. She is nicer and has better control over her temper than Alvin does, though it is still a bit shorter than most. She is also shown to have a much better, loving relationship with her sisters, becoming visibly concerned and defensive about them when her manager Ian tried to split them up. Unlike her cartoon version, she is able to apologize when she has judged wrongly.
In Alvin and the Chipmunks: Chipwrecked, her personality is a mixture of what she was like in the 80s and what she was like in Alvin and the Chipmunks: The Squeakquel. Sometimes, she and Alvin have hard times with each other, but they truly care for and appreciate each other
