Christina Aguilera, "Keeps Gettin' Better"

On last night's VMA's, Christina Aguilera "re-interpreted" her first smash, "Genie In A Bottle," before introducing her new single, "Keeps Gettin' Better."

Now that she's no longer vaguely a pin-up girl, it looks like Xtina is embracing the next natural progression: electropop trannie from outer space.
