It's been a good year for Britney. She has hair, for one thing, as well as a cushy job on The X Factor, where she gets plenty of publicity for sparring with Demi Lovato. But more importantly, she has a new puppy, Hannah. The little dog's Twitter account has almost 9,000 followers, probably due to compelling tweets like, "What should I chase today…squirrel or chipmunk? Arf arf!" Clearly she doesn't need to chase fame.
