People shared this article after talking to Keith & Nicole on the red carpet tonight … they discussed Keith’s song The Fighter.

Keith Urban may be the most nominated artist at Sunday’s Academy of Country Music Awards, but if you think that carries any clout at home with Oscar-winning wife Nicole Kidman and his daughters, think again.

“Everybody who’s married knows that’s an illogical question,” Urban, 49, told PEOPLE when asked if he can use his nominations to his advantage. “A ‘get out of jail free card’ does not exist.”

Aside from hopefully collecting some hardware at the awards, Urban will also perform two songs: “Blue Ain’t Your Color” and “The Fighter,” which he will sing with Carrie Underwood.

When he initially wrote “The Fighter,” Urban said he had Underwood in mind as a collaborator, and there wasn’t really a plan B.

What if she said no?

“I would have thought of somebody quick,” he said. “I would have had to have thought of somebody quick. I think if Carrie said no, we were set with the schedule and everything, we would have just had to leave that song off the record. That would have given me time to find the right person. I wouldn’t rush the wrong person in there just to make a record. Thank goodness she said yes.”

Later, on the official red carpet pre-show, Kidman, 49, opened up about what being the inspiration for “The Fighter” means to her.

“I remember when he first played it for me, and I started to cry because … he writes these things — they come out of I don’t know — and they’re like beautiful gifts,” the actress said.

Just hours ahead of the show on Sunday, Urban showed his daughters cheering him on with their own homemade sign.
