Keith Urban's big night at the CMT Awards on Wednesday night doubled as a romantic date night with wife Nicole Kidman. The couple looked like two kids in love as they hit the red carpet, giggling and whispering in each other's ears. Once inside, Keith hit the stage with Carrie Underwood for a beautiful acoustic rendition of their song "The Fighter." Keith also took home the award for male video of the year and gave Nicole and their daughters — Sunday, 8, and Faith, 6 — the sweetest shout-out in his speech. "I want to say a massive thank you to my wife Nicole," he said. "You have no idea how much of what I do . . . she's involved in every little piece of it. She hates me saying this, but I want it to be said. She helps me so much making these videos what they are. To our little girls at home, Sunny and Fifi, we're going to bring you next time for sure!"
