There's no one bigger than Lady Gaga. In a little over a year she's become a global pop sensation.
"Whether you like her music or not, you cannot deny how compelling she is," Callahan says.
The New York Post's Maureen Callahan has written the first biography about the star. It's called Pokerface: The Rise and Rise of Lady Gaga. In it, she drops the bombshell: Lady Gaga's handlers didn't think she was pretty enough to be a pop star.
"They thought maybe she didn't have the sort of commercial, ready-made looks that a Britney Spears or a Beyonce had," Callahan explains.
So the decision was made to create the Lady Gaga persona, with her outrageous costumes and over-the-top personality.
INSIDE EDITION's Lest Trent says, "You write that one NYU classmate said that at school she was quite normal."
"Her crazy outfit consisted of putting suspenders on her jeans," Callahan says.
For all of the fame, Lady Gaga may be a prisoner of her own success. According to the author, she's one of the loneliest people on earth.
"She cannot be alone, it's her worst nightmare. She needs somebody with her in the room at all times," says Callahan.
