Nicole Kidman explores the "Parallel Line" in surprise performance with Keith Urban

ABC/Image Group LAKeith Urban fans who turned out Monday night for a special Spotify preview of his new album got an extra surprise. Keith’s Oscar-winning wife, Nicole Kidman, joined him onstage to sing a few background vocals.

Nicole contributes BGVs to Keith’s most recent hit, “Female,” but this time, she also chimed in on “Parallel Line.” The Graffiti U track was co-written by pop superstar Ed Sheeran, and is Keith’s single in the couple’s native Australia.

Clad in a black-and-white printed dress, Nicole sat on a stool as she leaned into the mic, sang and smiled at her husband. You can check out a short clip on Keith’s socials.

Thursday, Keith stops by the syndicated The Ellen DeGeneres Show, prior to Friday's release of Graffiti U.
