Britney Spears: New and improved

After her much-publicised divorce with K-Fed (Kevin Federline), her ugly child custody battle, the bald and tattoo episode, and the brunette phase, our original pop princess is back, and how.

Britney Spears' newest album, called Circus, including the hit single, Womanizer, hit music stores on December 2, which incidentally also is her 27th birthday.

What do we love about her new look? While her Baby One More Time innocence is impossible to get back, we do get a small glimpse of what she looked like then. And that's good enough for us. Take a look and let us know what you think.
