"I do feel like we do have our own roles that we fall into and compliment each other," said Underwood.
"At this point three years later, we have each other pretty well figured out, so I think it will go really smooth," Paisley said.
Paisley said that Underwood's recent marriage to NHL star Mike Fisher won't be off limits when it comes to jokes, though.
"We have to bring it up," he said. "It was big news in country music, so if it is that, it is fair game, as well as Nashville or current events. It's worth talking about anything like that that people will relate to."
Underwood's multiple wardrobe changes won't be off limits either.
"I can't change anymore than I did last year," said Underwood, who changed more than 10 times. "I don't think that's a physical possibility, so I'm not going to try to outdo the costumes."
So maybe it's Paisley's turn to change his outfits this year?
"I think that would be awesome," said Underwood. "I'm going to stay in the same thing all night. I'm going to show up in my pajamas, and you're going to do your thing."
The 44th annual edition of the show will air live on ABC November 10. The nominees will be announced August 31 and September 1.
