Keith Urban could earn over $17 million after his unexpected separation from Nicole Kidman, largely due to a surprising prenuptial agreement linked to his sobriety.

The 57-year-old musician from New Zealand is said to have signed a prenup with Nicole, who is 58, before their marriage in 2006. This agreement grants him $900,000 for each year they were married, according to Radar Online.

However, the agreement includes a ‘Cocaine Clause’, indicating that Urban is entitled to this sum only if he remained free from drugs and alcohol throughout their marriage.

Across their 19-year marriage, the former power couple accumulated a massive property portfolio worth a reported $282 million. 

Urban has long been open about his past struggles with addiction. 

In a 2010 interview with Oprah Winfrey, he recalled how Nicole staged an intervention just months after their wedding. 

‘She made a decision to turn around and initiate ultimately this intervention. It was done in such a way that the love in that room at that moment was just right. I was like, “Put the cuffs on, let’s go”,’ he said.

He said the intervention saved his life and marked the start of his long road to sobriety – all with Nicole by his side.

The couple, who share daughters Sunday Rose, 17, and Faith Margaret, 14, have been living apart since early summer. 

Urban moved out of their Nashville mansion while on a music tour, while Nicole stayed behind with the kids and juggled a busy filming schedule in London, renting a lavish mansion for $87,000 a month while shooting the Practical Magic sequel.

Sources say the split grew more noticeable after the death of Nicole’s mother in  September 2024: ‘It’s like they both went their separate ways,’ an insider told Woman’s Day.

Their last public appearance together, at the FIFA Club World Cup 2025 match in June, hinted at tension. 

Body language expert Louise Mahler noted Kidman was ‘fiddling with her left hand,’ while Urban avoided eye contact – a far cry from their usual displays of affection.

Urban has previously spoken about how close their marriage came to falling apart. 

At the AFI Life Achievement Award Gala last year, he admitted: ‘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.’

Despite the split, sources suggest a reunion is still possible – though their busy schedules keep them apart. 

Urban continues to tour, while Nicole balances family life with her filming commitments.

Back in June last year, Urban stunned the A-list crowd while honouring Nicole at the AFI Life Achievement Award Gala Tribute when he candidly revealed that his addictions almost blew up his marriage.

‘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 began. 

Keith admitted he was battling addiction at the time he met Nicole. 

But with her support, he eventually managed to 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.’

‘Nic pushed through every negative voice – I’m sure even some of her own – and she chose love.

‘And here we are tonight 18 years later. Her capacity to love is like no one I’ve ever met.’
