Who's that girl??

Ok, remember Beyonce mentioning that she has an "out of body" experience being "Sasha" (her made-up character) that gives her extra confidence when she's performing...Well, I guess "Sasha Fierce" is her alter ego or something. Either way, Beyonce or Sasha, she can work the stage when she's entertaining.
Go Girl! I guess, this is like T.I. being T.I.P and T.I. and you get confused because you don't know which one he is trying to be. LOL
