LOS ANGELES: Lady Gaga is laughing off "ridiculous" rumours she has both male and female reproductive organs.

Recent Internet footage of the Poker Face singer onstage has sparked fresh debate as to whether or not the hitmaker is a hermaphrodite - because a bulge can clearly be seen.

And now gossip website HollyScoop.com reports Gaga actually addressed the rumours of her sexuality with a blog entry at Christmas (08).

The website claims the singer wrote, "It's not something that I'm ashamed of, just isn't something that i go around telling everyone. Yes. I have both male and female genitalia, but i consider myself a female."

However, the star's manager tells ABC News, "This is ridiculous."
