Internationally celebrated for her wildly original performances, Lady Gaga may have a wildly unoriginal habit: going hungry to look good onstage. A new biography penned by Maureen Callahan, 'Poker Face: The Rise and Rise of Lady Gaga,' reveals startling claims about the seemingly confident singer, according to RadarOnline.

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.
