There's a new Spears girl in the family!
Britney Spears showed off the latest addition to her brood this morning on Facebook -- formally introducing her followers to her new puppy, Hannah.
"I want you all to meet my new little baby girl Hannah ♥ How cute is she?!?!", Spears posted along with the shot, which appears to have been taken backstage at "X Factor."
We first spotted the dog when Britney stepped out carrying her during a Starbucks run last week ... and we can't wait to see more of her!
The only question we have: Whatever happened to Bit Bit?
