Nicole Kidman and Keith Urban are officially ending their marriage. PEOPLE confirms that the actress filed for divorce on Tuesday, September 30, in Nashville, citing irreconcilable differences. 

The filing comes just one day after news of their separation broke, with TMZ first reporting the story. Kidman listed their date of separation as the same day she filed, formally closing a chapter that began in June 2006 after they met at a Los Angeles gala the previous year. The couple shares two daughters, Sunday Rose, 17, and Faith Margaret, 14.

Sources tell PEOPLE that Kidman, 58, “didn’t want this” and had been “fighting to save the marriage,” leaning on her sister Antonia and the Kidman family for support during the difficult period. The split follows a summer apart – Kidman was filming Practical Magic 2 in London while Urban, 57, was on his High and Alive World Tour, highlighting the distance that had been quietly growing between them.

While the filing is official, eagle-eyed fans had already noticed signs that the couple’s relationship was under strain. Here’s a closer look at what tipped fans off over the past months:

Their last big public outings together were the CMAs in May, where they seemed happy and playful, and a Nashville soccer match in June. After that, they were rarely photographed together, signaling that something was shifting behind the scenes.

5. Awkward Interviews

In July, Urban abruptly ended a Zoom interview when asked about Kidman’s steamy scene with Zac Efron in A Family Affair. Insiders say he didn’t want to discuss his wife publicly, which suggested tension and discomfort in the marriage.

Just days before his split from Kidman was confirmed,  Urban made a surprising tweak to his song “The Fighter,” originally inspired by their relationship. During a recent concert, he changed the lyrics to give a shoutout to touring guitarist Maggie Baugh, singing, “When they’re tryna get to you, Maggie, I’ll be your guitar player,” leaving the 25-year-old stunned and sharing the moment on Instagram. 

For fans who’ve followed their relationship, these hints made the split feel less like a shock and more like the confirmation they’d quietly suspected. Even Hollywood’s golden couples face challenges, and sometimes love simply needs space to evolve.
