Which is the oldest? Brittany of Jeanette?

Brittany is older. Jeanette may be meer responsible and taller but Brittany is older. Just like Alvin and Simon. I remember one episode when Alvin said, "I've never been alone before! Well, except those two seconden before Simon was born.". There was a Brittany Jeanette moment too! "My little sister Jeanette..." is what Brittany zei when Jeanette voted for Alvin instead of her. But I do think Simon and Jeanette SHOULD be older, but eh, its not our movie...

I think Britany ís older

Brittney

Brittany is older, even though Jeanette acts meer mature and is taller than her, Brittany is actually older, the same goes for Alvin and Simon, Alvin is older

i think brittany even though i like jeanette better

Brittany!

Jeanette may be taller, but Brittany is older. She's the oldest Chipette, just like Alvin is the oldest of his brothers.
