Lady GaGa denies hermaphrodite rumours

Lady Gaga has branded claims she is a hermaphrodite "ridiculous".

The 'Poker Face' singer furiously denied rumours she has both male and female genitalia, insisting the speculation has gone beyond a joke.

The 23-year-old star told Australia's Matt and Jo radio show: "It's too low brow for me to even discuss. I've made fun of it before but to talk about it is ridiculous."

Gaga - whose real name is Stefani Germanotta - has previously made light of the claims, jokingly posting on a blog: "I have both male and female genitalia, but I consider myself a female."

Meanwhile, the outrageous star has revealed she spends her free time watching her own concerts on YouTube.

She said: "I like to watch my performances sometimes. I'm always trying to improve on choreography and the stage shows. I like to watch the lighting.

"I often argue with my lighting designer on the show - as much as I like to light the show for the room, it's important to light the show and design the sound for YouTube.

"In truth, lots of my fans can't make it to my shows in Israel or Germany or in Paris, so they go online to watch them."
