"You can't say no to Mariah," Cowell, a huge fan of Carey's, tells PEOPLE
Whatever Mariah Carey wants, Mariah Carey gets.
“You can’t say no to Mariah,” Cowell, 51, tells PEOPLE. “We have to find a role for her. I’m a huge fan of hers – not just as an artist, but as a person, and I love her to death.”
But Cowell also says that having Carey on the show poses a slight problem.
