Nicole Kidman has filed for divorce from Keith Urban amid their monthslong separation after nearly two decades of marriage.

The 58-year-old Oscar winner filed Tuesday, People magazine confirmed, a day after sources told TMZ that she and the Grammy winner, 57, had been living apart “since the beginning of the summer.”

The couple wed in June 2006 and share daughters Sunday, 17, and Margaret, 16.

Earlier Tuesday, insiders with links to the “Big Little Lies” star told TMZ that “all the signs point to the fact Keith is with another woman.”

“Let’s just say, Nicole doesn’t dispute that, but she’s still shocked over it,” the sources continue.

Another said that rumor is “all over Nashville,” which the Aussie stars have long considered home base. Urban reportedly moved out of the family home there and into his own place, as a source told TMZ Monday.

The “Babygirl” actress — who sported her wedding band at an event just last week — “didn’t want” to separate and “has been fighting to save the marriage,” a source told People.

“The split was kind of inevitable” in the eyes of Urban’s friends, amongst whom it “really hasn’t been a secret,” said another insider.

It’s unclear when things took a turn for the irreconcilable. Speaking to People in April 2024, Kidman referred to Urban as “my love, my deep, deep love.” That month, while honoring Kidman at the 49th AFI Life Achievement Award Gala that his addictions “blew our marriage to smithereens” when they were newlyweds.

“Four months into a marriage, I’m in rehab for three months,” said Urban, adding his wife “pushed through every negative voice … and choice love. And here we are tonight, 18 years later.”

Urban last posted Kidman in May of this year, shortly before embarking on his world tour. Their most recent appearance together was at a 2025 FIFA Club World Cup match in June, the same month that Kidman shared a black and white portrait to celebrate the couple’s 19th anniversary.

Days later, the country star hung up on a radio interview when he was asked how he feels about Kidman’s love scenes with the likes of Zac Efron. By July, Urban’s name was nowhere to be found when Kidman applied for residency in Portugal, for which Urban was absent, ostensibly due to the tour.
