LADY GAGA GONE

ABOVE: Pals think Lady GaGa could be going ga ga

LADY GaGa is on the brink of a Britney Spears-style meltdown, it is feared.

The triple Brit Award winner admits the stress of her success is causing “blinding headaches and blurred vision”.

She was forced to cancel gigs on the US leg of her Monster Ball tour after collapsing with severe breathing problems backstage.

And paramedics in West Lafayette, Indiana, warned her she could be suffering respiratory problems that require urgent attention.

The 23-year-old brushed aside their concerns, declaring: “I’ve resigned myself to this ridiculous schedule because I feel it is my destiny to provide for my fans.”

But close pals of the wacky singer – real name Stefani Germanotta – believe the pressures of fame are drastically affecting her off-stage behaviour.

And experts believe the strain of constantly playing to the cameras could be unsettling her mentally.

Los Angeles psychotherapist Jane Martinez said: “No one can put on an act 24/7. The almost inevitable result of this action is a mental and physical breakdown somewhere down the line.”

Before flying to London to accept her Brit Awards last month, she strolled into trendy Desmond’s Tavern in New York wearing an outfit too revealing even for her outrageous stage show.

Tavern owner Hugh Connolly said: “She was in fishnet stockings and a top – but had no pants.”

Before that, GaGa – who appeared on Jonathan Ross’ show on Friday night – fired several members of her staff after her dress almost fell off during a performance on the Oprah Winfrey Show.

She has also issued bizarre personal demands of Monster Ball tour promoters.

In Dublin, her backstage rider demanded a spiritualist, a tarot card reader and a “non-smelly cheese on ice”.

Pals say she’s been “close to the edge” after her father had open heart surgery last October.

Weeks later, she split from long-time boyfriend, a 31-year-old US millionaire known simply as Speedy, amidst claims of cheating.
