Most showbiz splits don’t surprise. Nicole Kidman and Keith Urban, though?

That’s one we didn’t see coming.

Are they odd? Yes — but in a way that seemed well-matched.

The couple displayed a contradiction between their seemingly cheerful personalities and their meticulously crafted public images. One sign that hinted at trouble in their relationship was their exaggerated displays of affection, such as excessive cuddling and kissing during public events like premieres and award ceremonies.

Secure couples who are in love and enjoy a healthy sex life don’t feel the need to prove it — let alone ALL. THE. TIME.

So, what is it they were trying to convince the public of, exactly?

Most showbiz splits don’t surprise. Nicole Kidman and Keith Urban, though? That’s one we didn’t see coming

Kidman, 58, and Urban, 57, did share a lot of similarities. Both were Australians who moved to the United States and had long aspired to be in the performance industry since their youth.

Neither one finished high school. Kidman once revealed in a radio interview that she dropped out at age 16, while Urban left at 15.

‘We shouldn’t be putting that out there,’ her husband interjected, with a laugh. ‘It’s not a good promotion.’

But that was hardly Urban’s biggest secret.

As the story unfolds about their split, which Kidman officially started by filing for divorce on Tuesday, whispers blame her unending ambition and desire to keep working as a contributing factor.

‘Keith never sees Nicole,’ one source said.

Note the order — it’s not that Nicole never sees Keith, even though both have demanding careers.

Even though Urban is a touring musician. Kidman, at least, is locked into any given location for weeks or months on end.

But we are meant to believe that it’s her ambition, her careerism, that broke this marriage.

The idea that Kidman, possibly experiencing a midlife crisis, is eager to accept roles featuring explicit scenes with younger men to reaffirm her allure, is a notion that seems plausible to some.

Subtle, she is not.

In promoting one such film, 2024’s BDSM-themed Babygirl, Kidman said this in an interview:

‘There were moments during filming when I just thought, ‘I can’t handle this anymore.’ It didn’t matter to me if I never experienced physical intimacy again. It felt so overwhelming, like burnout.’

Urban, who has been on tour since May, appears to be working this angle too.

A source revealed to the Daily Mail that their relationship lacks closeness. The couple is merely going through the motions of marriage, with Keith having to confront her about his discontent.

That was Monday.

On Tuesday, longstanding rumors in Australian media — that Urban has been seeing another, much-younger woman for quite some time now — were apparently confirmed.

And by Team Kidman, no less. She may be odd, but she’s no dummy. She surely sees that Urban’s trying to depict her as the villain here.

‘All the signs point to the fact Keith is with another woman,’ a Kidman source told TMZ.

‘Let’s just say, Nicole doesn’t dispute that. But she’s still shocked over it.’

Is she, really? Because Urban was slippery from the outset, before they began dating.

If anything’s believable, it’s that what seems like an ongoing midlife crisis has led Kidman to take every role requiring explicit on-screen sex with younger men to prove her sexual viability

‘I remember thinking, I had such a crush on him, and he wasn’t interested in me,’ Kidman said in 2017. ‘He didn’t call me for four months.’

‘I thought she was way out of my league,’ Urban said the following year. ‘Not in a million years did I think that somebody like that would be interested in me. At all.’

They were engaged within months of dating and married in June 2006. Kidman cemented her commitment just four months later when Urban, a former crack cocaine and booze addict, relapsed on alcohol and entered rehab in Palm Springs.

Two months later, on Christmas Eve, the Daily Mail published an exclusive interview with part-time model and Nashville resident Amanda Wyatt, who claimed she and Urban had been involved throughout his relationship with and engagement to Kidman.

Urban denied the allegations at the time.

‘I feel sorry for Nicole,’ Wyatt said. ‘Keith cheated on her repeatedly with me, right up to just before they got married.’

Wyatt said she was 21 when they met in 2004. Urban was 16 years older.

Perhaps Wyatt was one reason Urban took four months to call Kidman after they first met.

‘He told me he loved me,’ Wyatt said, adding that Urban was known to still be drinking and using drugs.

‘As I got to know him, it was clear he was a deeply troubled man,’ she said. ‘He drank constantly. His favorite was Crown Royal Reserve whisky. And he did drugs: Ecstasy, cocaine, pot — you name it… I rarely saw him sober.’

Wyatt said that after she saw photos of Urban and Kidman together, she asked about it, but he wouldn’t say a thing. They continued having unprotected sex, she claimed.

‘He told me he longed for a child,’ Wyatt said. ‘I sometimes wonder if he said the same thing to Nicole.’

Kidman was no stranger to difficult divorce, having infamously been dumped by Tom Cruise just after their 10-year wedding anniversary.

So why would she stay in an already brief marriage founded on apparent lies of sobriety, fidelity and honesty?

Perhaps she wanted this one to work. Perhaps she didn’t want to be twice divorced. Maybe she thought, as so many women do, that she could ‘fix’ him.

Of course, that never works.

For the sake of their two teenage daughters, the best Kidman can hope for is a relatively clean split — but who are we kidding? Both sides already appear to be slinging mud.

As Urban’s alleged one-time affair partner said all those years ago: ‘I hope their marriage works — but leopards don’t change their spots.’
