"I invited them to hockey games! I always am like, 'You guys should come!'" Underwood revealed of her plans to get Urban and Kidman together with her and her husband, Nashville Predators captain Mike Fisher.
"Dates are few and far between at this point in our lives just because the season is so crazy," she added, "but I know they've come to games before, so hopefully I can get 'em out!"
Underwood and Urban will go head to head, as they're both nominated for Best Country Solo Performance (Underwood for "Church Bells" and Urban for "Blue Ain't Your Color") -- but they're no stranger to competition. The pair star side-by-side in a boxing-themed music video for their duet, "The Fighter," which they're performing together during the show.
"It's a joyful song! It's such a fun song. It's a dancing song, and I feel like that comes through in the video," she explained. "We were having fun all day long shooting it, so we were just trying to match the energy of the song."
As for how Underwood gets in fighting shape, she says it's often about scheduling exercise around her son's routine.
"I do whatever I can and make time for it. Isaiah goes down for a nap, I've been in my workout clothes all day long, I'm there, I'm ready, I make it happen," she said. "If it's 15 minutes, that's good. If it's an hour, that's great. It just happens when and how it happens."
Still, Underwood admits to a little extra help getting into her gorgeous Elie Madi GRAMMYs gown.
"I am taped in!" she laughed. "We're going to have to peel this dress off me because I am taped in!"
The 33-year-old singer also offered words of advice to Best New Artist nominees Kelsea Ballerini and Maren Morris.
"You know, as a woman in the music industry, you just got to bring it," she told ET's Sophie Schillaci. You gotta work three times as hard as the guys and just make sure you are willing, and they are definitely."
