Was Lady GaGa Really A Man?

Rumor has it that Lady GaGa used to be a man, and she had a sex change to become a woman.  I find this hard to believe, but anything is possible.  She likes to show off her body in many of her music videos, and a lot of times she has things covering parts of her face.  I really don't care if she used to be a man or not, I still love her music and I'm not afraid to admit it.  What do you think?
