Is she a man? Well, "Lady" Gaga insists she's not.
GaGa, real name Stefani Germanotta, had refused to comment on Internet speculation about her gender after a series of photos published on forums showed her in an unflattering light, reports News of the World.
However, she's denied the rumour, adding: "At first it was very strange. But, in a sense, I portray myself in a very androgynous way. I like pushing boundaries."
The Bad Romance singer, 23, also revealed that her bisexuality inspired her hit Poker Face.
She said: "I have had sexual relationships with women. But I've only been in love with men. That was really what Poker Face was all about. Why, when I was with my boyfriend, was I fantasising about women?"
