Nicole Kidman and Keith Urban split after 19 years of marriage

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.

It wasn’t immediately clear if the now exes are planning on getting a divorce.

The “Big Little Lies” actress and Urban tied the knot on June 25, 2006 — nearly a year after first meeting at the G’Day USA gala in January 2005.

Kidman was previously married to Tom Cruise from 1990 to 2001. She and the “Top Gun” actor share two kids: Bella, 32, and Connor, 30.

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