A new biography written by Maureen Callahan, ‘Poker Face: The Rise and Rise of Lady Gaga,’ reveals startling claims about Lady Gaga’s extreme dieting.

Gaga’s former tour manager, David Ciemny, alleges in the book that the 24-year-old binged on junk food when not depriving herself of calories altogether. And he claims that in 2009 alone, the Grammy winner landed in the hospital six times while dieting to slim down. Not once, not twice, but six times last year.

That was last year. This year we know of least two more incidents that landed Gaga in the hospital. In March she nearly collapsed onstage, seemingly exhausted. And in April, the pop star’s rep denied that Gaga was on a baby-food only diet. She denied it of course…but it isn’t hard to believe that she might go to such extremes. She is such a darling among fashion insiders and most in that world will do whatever it takes to be as tiny as possible.
