Keith Urban takes a swipe at Nicole Kidman marriage on ‘The Road’

Keith Urban seemingly took a swipe at his apparently unpleasant marriage to Nicole Kidman before she filed for divorce.

During Sunday’s series premiere of “The Road” — which follows 12 emerging musicians competing to be Urban’s opening act while he tours across America — he took the stage to sing his song “Straight Line” off his most recent album, “High.”

Urban, 57, reflected on the message behind the track in February 2024, telling his Instagram followers that it’s about “wanting to break out of a soul-sucking routine that you might be stuck in.”

He elaborated, “Maybe in a relationship, a job, with creativity, with yourself…whatever it is!!”

The country singer explained that he wanted the song to convey the idea of “feeling alive again and getting out from under that dark cloud.”

“Straight Line” is the first track on the album “for a lot of reasons,” but particularly because “it represents an energy and spirit that became a through line of the whole record,” he shared.

Urban told his fans he was “gonna cover a lot of themes, emotions and vibes on this album but a very human spirit runs through them all.”

At another point during the competition show, the musician complains about being “lonely and miserable” while reflecting on the hardship of touring, noting that the show must go on no matter what is going on in one’s personal life.

News broke in late September that his and Kidman’s 19-year marriage was coming to an end.

“Sometimes relationships just run their course,” a source told us at the time, adding that the actress, 58, “did not want the separation and was trying to save things.”

Kidman — who shares daughters Sunday, 17, and Faith, 14, with Urban — filed for divorce the following day.

Rumors then began swirling that Urban may have been romantically involved with his guitarist Maggie Baugh, though the speculation remains unconfirmed.
