After long months during which Britney Spears has been the laughing stock of the entire world for the way she behaved (and looked) in public, the once multi-platinum Princess of Pop is back. As she promised, Britney showed her rocking new body during a surprise visit she made on the set of David Letterman's show.

To sum the appearance that lasted less than a minute, Brit looked more like her old self than she had, like, in ages!

Wearing a very short black dress that almost rode up her butt and with a new blonde (finally!) hair-do, the singer was all smiles and kisses for the audience who couldn't stop screaming when she came on.

Although the purpose of the visit is not for one second clearly stated (that of beginning to re-launch herself in showbiz), it was pretty obvious that the star got exactly what she wanted from the world: make people crave for more. She told Letterman that she just dropped by, because she was in town and just had to come over and talk to him, being such a great fan of his as she is.

Then, she walked out, allowing people in the audience a full view of her behind and legs. And, truth be told, she did look stunning. Just click HERE or HERE to see the short footage. Certainly, there must be thousands of fans out there who can hardly wait for her (also promised) next album to come out! Way to go, Britney!
