Jeanette Miller can be described as the absent-minded professor of the Chipettes. Gifted with extroardinary intelligence, she is often so caught up in the studies of the universe that she forgets the simple matters of life, such as not tripping over her own feet. Despite that she is the eldest of the Chipettes, she is too timid to stand up to her younger yet overly domineering sister, Brittany.Jeanette has brown hair and green eyes, and her signature colors are navy blue and purple. She also has very poor vision and is helpless without her glasses. She shares a quiet yet romantic relationship with Simon Seville, a member of the Chipmunks. Jeanette and Simon do care deeply for each other but are both too shy to admit that they love each other.
