Nicole Kidman and Keith Urban have separated after 19 years of marriage, Page Six can confirm.

“Sometimes relationships just run their course,” a source tells Page Six Monday, adding that Kidman “did not want the separation and was trying to save things.”

The actress and country music singer have been living apart “since the beginning of summer,” multiple sources told TMZ, who was the first to break the news.

The outlet reported that Kidman has been caring for their two children: Sunday Rose, 17, and Faith Margaret, 14.

“[Kidman is] holding the family together through this difficult time since Keith has been gone,” a source said.

Urban has allegedly moved out of their family home in Nashville, Tenn., and purchased his own property in the same city.

“Keith has acquired his own residence in Nashville and has moved out of their family home,” which is also in Nashville.

Reps for Kidman and Urban did not immediately return Page Six’s request for comment.
