While Carrie Underwood is in Australia, touring with Keith Urban, she made a stop at the local news show The Project. But she stopped them before they pushed her too hard on yodel-ay-ee-oooo.

"I can yodel. I did, and no, I will not right now. Because then everywhere I go people will be like, 'Yodel.' It's too much," Underwood laughed.

She also explained how she found out about her Grammy nomination for best country solo performance for "Church Bells."

"I woke up, and of course the time difference is giant," she said. "I usually wake up to lots of texts, and that was one of them. And I was like, 'Excuse me? Like what?' My clock is so off -- it's yesterday, we're in the future somehow -- so I'm just trying to figure it all out."

She also talks about babyproofing the tour bus, her growing Australian fan base and how much she gets working moms now.

"My mom was a working mom, and you just kind of take it for granted until you're in this position," she said. "And I just gained a lot of respect for moms, just doing what they do and working hard."

Especially when there are some nights you sleep, and others you don't. So what does she do when she's running on empty but has an arena full of fans there to see her?

"I can go on stage kind of tired, and be like. 'Oh man, I hope I can muster up enough energy. And then there's just so much energy coming at you from the crowd.

"And when I walk off stage," she said, "I'm like, 'How am I gonna come down from this?'"
