Los Angeles - Is she male or female? This raging question is being asked of Lady Gaga.

Clips on YouTube - with titles such as 'Lady Gaga Hermaphrodite' - has fuelled the rumours of the pop star.

They show the singer performing at Britain's Glastonbury festival in June, with a distinct bulge under her short outfit. Her manager denied the reports, saying they were 'completely ridiculous'.

To singer Katy Perry, it was all 'calculated' by Lady Gaga.

She told London's Daily Mirror: 'Oh, please. It's all very calculated. She knows what she's doing. She put something in her knickers, a mini strap-on.'
