"No, no. I'm sure they'll have huge numbers after the Super Bowl. Any show after the Super Bowl will have huge numbers," he replied.
"Listen, they've got a great show and I think there is room for everyone out there, as you will see."
Discussing American Idol's ratings for its current 11th season, he said: "It's still the number one show in television, not by the huge margins it was before, but I think just in the term of time…
"Also, I think the space of singing shows is definitely a little crowded right now. They are on year round with us, The Voice and X Factor, and there's even singing on America's Got Talent."
He added: "You got a lot of singing and that's what happens when the market place gets full."
