I swear, it's muscle memory. Like riding a bike or forgetting to lift the seat when you take a whizz, it's all muscle memory. And while much of the world laughed when older, fuller-bodied Britney Spears launched her Femme Fatale Tour, including yours truly, well, in your face, because Britney Spears definitely flipped the inner-sextastic switch, hit a new gear about halfway through her concert tour. Britney actually seems to be getting fitter and sexier and finding her old moves as the tour moves along. Who knows, by the final dates, she may be trim and making out with chicks again on stage. It's all there, she just needed to find it again. Enjoy.
