Beyonce Wants To Be Wonder Woman Something Rotten This is getting confusing - first Beyonce told us that she was Sasha Fierce, and now she might be Wonder Woman as well. Beyonce, that is. Not Sasha Fierce. Unless Sasha Fierce wants to be Wonder Woman instead of Beyonce. But at the moment we just think that it's Beyonce who wants to be Wonder Woman, and Sasha Fierce hasn't got anything to do with it. Except that Sasha Fierce is Beyonce, so technically they both want to be Wonder Woman. Clear? Good. Beyonce wants to be Wonder Woman in a new movie. Which sort of makes sense. She's got the thighs for it, we suppose.
