Carrie Underwood would be a "constructive" X Factor judge.

The country starlet thinks she would be a great addition to the judging panel of Simon Cowell's singing competition, but worries she wouldn't be able to cope with shattering wannabe musicians' dreams.

"I'd never say never. I think I could do things in a very constructive way. But those initial auditions, where you have to say no or tell someone to stop? I don't know if I could do that," she said.

The blonde beauty also revealed she would love to collaborate with British acts including Oscar-winning Skyfall singer Adele. Carrie listed, "I love Jessie J, I think she's fearless, which is great. Coldplay. Adele, of course. I'm up for anything."
