This isn't the first time the couple has collaborated. Kidman sang background vocals on Urban's single "Female." In 2016, the couple posted a video of them singing Urban's hit song "The Fighter" together.

Urban's new album Graffiti U will be released on April 27. The album is a 13-song collection, featuring "Parallel Line" and "Female." Earlier this year, the singer announced the album and gave fans a peek at what's to come at a pop-up show at Nashville's Exit/In.

Last month, Urban released his latest single "Coming Home," featuring pop singer Julia Michaels. The song samples Merle Haggard's "Mama Tried" guitar riff.

He'll kick off his Graffiti U World Tour on June 15 in St. Louis, Mo.
