Nicole Kidman and Keith Urban’s model daughter has returned to social media for the first time since her superstar parents confirmed their marriage is over.

Kidman announced her separation from country star Urban on Tuesday, effectively drawing a line under their once rock-solid 19-year marriage. 

But daughter Sunday Rose, the eldest of Kidman’s two children with the musician, was back at work just 24 hours later as French couture brand Christian Dior unveiled its latest collection at Paris Fashion Week.

The 17-year old model walked the catwalk on Wednesday, before using her social media platform to praise the spring-summer presentation by sharing video footage of her appearance.

Captioning the post with a series of credits to the creative team behind her latest show, she wrote: ‘j’adore dior.’

Kidman filed to end the marriage on Tuesday – citing irreconcilable differences – as a source claimed to the Daily Mail that Urban has already moved on with a younger woman in the music industry.

The well-placed Nashville music business PR source said: ‘The rumor is that he’s with a younger woman in the business. It’s all everyone is talking about. Everyone wants to know who, but so far, that’s a mystery.’

The Daily Mail has contacted representatives for Nicole Kidman and Keith Urban for comment. 

The former couple share daughters Sunday Rose, and Faith Margaret, 14.

Kidman was previously married to Tom Cruise, 63, for 11 years from 1990 to 2001. They adopted two children together: Isabella, 32, and Connor, 30.

At this time, Urban who is renting his own home in Music City, is allegedly showing no signs of wanting to reconcile.

Those in Kidman’s circle claim the very the suggestion of him with someone else after their separation has been difficult for her to process.

The couple were last seen together publicly in June this year, when they were pictured attending a FIFA World Cup match in Nashville, Tennessee.

The country star has been away for much of the year on his High and Alive World Tour. He is due to perform in Hershey, Pennsylvania on Thursday.

Kidman and the children, meanwhile, have remained in Nashville, where the couple own a $4million compound.

In July, Urban dropped a hint that all was not well between the pair when he dramatically hung up during a phone interview with a radio station after a crude question about Kidman’s raunchy recent scenes, such as in her movies Babygirl and A Family Affair.

For her part, and while promoting her Netflix series The Perfect Couple back in September last year, Kidman admitted there was no such thing as a ‘perfect’ marriage.

‘There’s no perfect anything,’ she said, ‘anything that’s presented as perfect… forget it.’

Earlier that year, Kidman said she was ‘so lucky’ to have met the singer.

‘I’m so lucky that I have Keith who’s just my love, my deep, deep love,’ she told People magazine.

‘I’m so lucky that I have Keith… that gives me the ability to go and do whatever I have to do because I know where I can come back,’ she added.

The pair married in 2006 during a traditional Catholic ceremony at the Cardinal Cerretti Chapel in Kidman’s hometown of Sydney.

She welcomed Sunday Rose in July 2008 and Faith via surrogate two years later. 

In 2022, Urban insisted that he and his wife are ‘as normal as you get’ on an episode of Jessica Rowe’s podcast series The Big Talk Show.

He also spoke about the very first time they met at the G’Day LA event in 2005, saying he thought the stunning Hollywood star was ‘well out of his league.’

‘We’re just a couple who work things out, go through things together, life, and support each other the best way we can and try and raise our family,’ Urban explained.

‘Underneath it all, we’re as normal as you can get I reckon,’ he claimed, before reflecting he was ‘not in a great place’ when they first met.

‘[She] seemed well out of my league at that time in my life,’ he said.

‘I was not in a great place at my life, struggling with a lot of things, not in a million years would someone like that see anything in me… The fact that became what it is meant to be is astounding.’

He also described his wife as ‘ethereal, angelic, other worldly, very mystical and then completely down to earth at the same time and very funny.’

Last year, Urban reflected on how he nearly destroyed his marriage, not long after they walked down the aisle.

‘We got married in 2006, and barely four months into our marriage, the addictions that I had done really nothing about blew our marriage to smithereens,’ he said while presenting at the AFI Life Achievement Award Gala Tribute to Kidman last year.

Urban revealed that he was struggling with addiction when he first met Nicole and with her support he managed to eventually pull through.

‘Four months into a marriage, and I’m in rehab for three months with no idea what was going to happen to us.
