The video also features images of him and Kidman playing around on a beach.
The Australian country star decided to use the clips, which were filmed by his longtime friend Chris Hicky, because of the personal nature of the song.
Talking about the video, Urban said: “I had Sunny with me on set and sat her down and just wanted to shoot a bit of her to keep for ourselves for our home movies. And watching her was the part that really moved me.”
He added: “I wanted all the images to fly by in a very dream-like way and not be so blatant. This song is obviously so personal and we’re obviously very private people so it was a question of how to balance that and honour the authenticity of the song.”
