nice song! the best since her collab with rihanna (which alot of her fans hated).

her interviews show the nice, sweet and sometimes amusing britney from old days. i agree that she hasn't aged well but the woman's been through a lot.

however i don't know about stories about her alledgely having 3 knee injuries. i remember when her 'oynox' tour started struggling she cancelled it, citing a knee injury. as much media coverage as she got (or gets) i missed hearing about her suffering from "3 knee injuries". jennifer lopez who is in her 40's has had several ankle injuries but is still fierce on the dance floor.

her kindness and personality sparkled through in her interviews; but the snippets of her performances looked disasterous. the dance moves of the 200 lb female host on superstarnova2 put britney's to shame (maybe it's me but i think it was kind of a tacky thing to do...it sorta put britney on front street).

britney should take another shot at comedic acting. she really has good timing. her performances in 'how i met my mother' and 'will and grace' were far better than what she's able to put out on stage nowadays.
