Keith Urban is said to be heartbroken after learning that his former wife Nicole Kidman has reportedly moved on with a new man.

According to New Idea, the 58-year-old country music star was 'absolutely devastated' by claims that Kidman, 59, had begun a romance with private-equity businessman Michael Reinstein following the end of their marriage.

The Oscar-winning actress was reportedly seen looking affectionate with Reinstein during a recent outing, with photographs appearing to show the pair holding hands and sharing a kiss.

An insider claimed the images came as a painful blow to Urban, who had allegedly continued to hope that he and Kidman might one day repair their relationship.

'Up until now, the door had been firmly closed on his relationship with Nicole,' the insider alleged.

'But now he still had hopes there might be a chance at reconciliation. He's absolutely devastated and is going through that feeling of deep loss all over again.'

The source further claimed that seeing Kidman apparently moving forward had prompted the Blue Ain't Your Colour singer to reassess his own romantic future.

'Seeing Nicole seemingly moving on is permitting him to do the same,' the insider said.

Urban is nevertheless said to be wary of entering a high-profile relationship, with the source claiming he would prefer to keep any future romance private.

'Don't be surprised if Keith steps out with a 'revenge romance' of his own,' the insider alleged.

'He knows he has to move on.'

Kidman and Urban were married for nearly two decades and share two daughters. 

It comes after Nicole was seen getting cozy with private equity businessman in exclusive photographs obtained by the Daily Mail. 

The Hollywood actress was seen sipping on an Aperol Spritz while sitting poolside with the silver fox in the Italian Riviera. 

The pair shared lighthearted conversations and at one point, Reinstein was seen playfully lifting up her hat, which protected her from the bright sunshine.

A source close to Kidman told the Daily Mail, 'After everything she went through with Keith, she deserves to find happiness.' 

The insider added, 'She never thought her marriage wouldn't work out and she tried as best as she could to keep her family intact.

'Her daughters are her best friends, and she seems really content in her life. She's so easy to get along with and kind. She keeps her personal life extremely private.'

In June reports surfaced that Kidman was romantically linked to a 'high-profile businessman.' 

According to online gossip site DeuxMoi, the pair have been taking things slow. 

A source told DeuxMoi at the time that 'the relationship has been quietly developing for the past few months and the pair have been keeping things extremely low-key and largely out of the public eye.'

The Moulin Rouge! actress had also been joined by daughters Sunday Rose, 18, and Faith, 15, during the Italian getaway. 

Kidman shares the teenagers with ex-husband Keith Urban.

Last year in September, the Oscar winner and Urban's separation came to light following 19 years of marriage, with the divorce being officially finalised in January.

It came after the pair had hit a rocky path in summer 2025, with the separation being reportedly a long-term development, according to Daily Mail sources.

Not long after ringing in the new year, the former couple reached a settlement agreement to finalize the divorce.

During an interview with Variety in March, Kidman opened up about the split and how she is now 'moving forward.'

'What I'm grateful for is my family, and keeping them as is, and moving forward. That's that.'

The Big Little Lies star added, 'I'm staying in a place of, "We are a family," and that's what we'll continue to be. My beautiful girls, my darlings, who are suddenly women.'

When questioned if she was 'doing all right' after the split, the actress replied, 'I am, because I'm always going to be moving toward what's good.'
