I like the way Keith Urban describes Mariah, it's similar to how Ryan Seacrest did. I don't know if it was posted, since I haven't been here in a few days. It was in those short Idol videos that Mariah, Keith, Randy and Nicki did.
But he said: "I think all four of us try our best to get [the contestants] to breathe. Mariah is great at that. She's like take a breath, take your time. She is very maternal. And, ya know, helps them to get in their zone more than any of us."
