With her headline-grabbing outfits and wild stage antics, it's safe to say Lady Gaga's no stranger to controversy.
But a shock new book by celeb biographer Ian Halperin accuses the singer, 25, of being a lonely, drug-abusing, weight-obsessed woman who's completely lost touch with reality.
While her reps emphatically deny Ian's claims, calling the entire tome a ‘fabrication', Gaga's said to be utterly devastated that she's been targeted by the author, who's also penned controversial books on Brangelina and Michael Jackson.
Canada-born Ian says: ‘From heroin to cocaine and ecstasy, her friends say Gaga has done every drug conceivable.'
He also claims she goes days without eating, adding: ‘She's obsessed with her weight.
'One friend told me Gaga will stare at herself in the mirror for hours on end, analysing and critiquing her body.
'It's an unhealthy obsession.'
