Which is the oldest? Brittany or Jeanette?

Brittany is older. Jeanette may be more 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 seconds before Simon was born.". There was a Brittany Jeanette moment too! "My little sister Jeanette..." is what Brittany said when Jeanette voted for Alvin instead of her. But I do think Simon and Jeanette SHOULD be older, but eh, its not our movie...

Brittney

Brittany is older, even though Jeanette acts more 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
