Brittany is the lead singer and eldest sister of the Chipettes, and is the female counterpart of Alvin. She has a pleasing facial and physical appearance, but at times can be vain and self-serving with the extreme desire to have whatever she wants. Often Brittany is happy to outdo others she dislikes, mainly this is shown when her arguments with Alvin grow into bets. This often establishes the plot of the episode. She has auburn hair which is seen in a stylized ponytail, blue eyes, and her signature color is pink. In the 2009 film, Brittany is voiced by Christina Applegate.
