"You never know what's going to happen with us hosting," Underwood joked.
She added: "I think being nominated — especially when hosting the CMAs — you just never know."
The CMAs take place Nov. 6 in Nashville.
Underwood also spoke about recording the opening number this season for "Sunday Night Football." She claims doing it was a no-brainer.
"It's a lot of fun. I grew up watching football. I'm from Oklahoma, it's what we do," she said with a big smile.
The conversation then turned to hockey and her husband Mike Fisher's team, the Nashville Predators.
"They got off to a little bit of rocky start, but definitely getting some momentum. I feel like my husband right now. I know what he feels like now. I feel there's some really great, new young talent," Underwood said.
And what about the team's star center?
"My hubby, he's been out for the past couple of games with a foot fracture thing. But he'll be back on the ice, ASAP. I hope he does, because that's the only way I get to see him, other than iChat."
