Does she still have it? Britney’s upcoming E! documentary special, 'I Am Britney Jean' debuts tomorrow and after years of rubbish performances, Ms. Spears wants the world to know she is back. The singer is seen rehearsing a "demanding" routine with her choreographer Antony Ginandjar. The footage does not give us enough to determine the full extent of her energy levels but it's unrealistic to expect her to move the way she did during her magnificent 'In The Zone' era. How much she's improved, only time will tell.
