Nicole Kidman and Keith Urban have separated after almost 20 years of marriage.

Variety confirmed the news of the split on Monday night, with an unnamed source telling the New York Post, “Sometimes relationships just run their course.”

The 58-year-old Australian actor and 57-year-old country music singer have been living apart since June, according to entertainment website TMZ.

In June, Kidman shared a photo of herself with Urban on Instagram to commemorate their wedding anniversary.

It is believed Urban has moved out of the couple’s Nashville home, and reports say Kidman is desperate to save the relationship.

“She didn’t want this,” another unnamed source told People magazine. “She has been fighting to save the marriage.”

The couple have two children together, Sunday Rose, 17, and Faith Margaret, 14. 

Kidman and Urban married in Sydney in June 2006, nearly a year after they met at the annual G’Day USA gala in January 2005.

Kidman was previously married to Tom Cruise from 1990 to 2001. She and Cruise share two kids: Bella, 32, and Connor, 30.
