Demi Lovato & L.A. Reid Video Q&A: 'X Factor' Judges Talk Simon, TV and Shunning the 'Sexy Route'

Demi Lovato didn't pull any punches when the "desert island question" was popped at last week's Billboard Film & TV Music Conference in L.A., choosing Britney Spears over fellow "X Factor" judge Simon Cowell. "Simon would be the biggest diva on the fricking island," she jokingly jabbed. "And he'd die within a couple years anyway because he's so old. I mean, he's only got a couple years left in him anyway, so"

Joined by her "X Factor" co-star L.A. Reid in a chat with Billboard editorial director Bill Werde, the "Give Your Heart a Break" singer opened up about her journey from Disney kid to a bonafide pop star. "I don't know how I did it, honestly. I'm open with issues, which makes me relatable," she said. "I never did the whole sexy route. I just don't feel comfortable onstage in risque clothes."

While discussing their show, Lovato and Reid offered some advice to future contestants. "If you're going to be there, you'd better be great. If [you're] great, [you'd] better be great in the first 30 seconds," the Epic Records chairman and CEO said. Lovato has a shorter fuse, saying "If they don't grab me in 10 seconds, I think, 'Done.'"
