Joint monthly income of Nicole Kidman and Keith Urban revealed as alleged 'cocaine clause' could make him millions in divorce

The combined monthly income of Nicole Kidman and Keith Urban has been detailed after the actress filed for divorce after almost 20 years of marriage.

News of Kidman and Urban's split emerged this week, with Kidman filing court documents in Nashville, Tennessee, where the celebrity couple spend most of their time with their two children, Sunday Rose, 17, and Faith Margaret, 14.

Details surrounding their relationship have since come to light, including one alleged clause included in the couple's prenuptial agreement signed prior to their marriage in June 2006.

Dubbed the 'cocaine clause', the section allegedly stated that Urban, who has previously been open about his struggles with substance abuse, would receive $600,000 from Kidman for every year they were married, and in which he said no to drugs and alcohol.

Over 19 years of marriage, this amounts to just over $11 million.

Considering $600,000 is a lot more than many people make in a year, news of this alleged clause naturally makes you think about just how much Kidman earns, with her net worth estimated to be $250 million.

Urban's, meanwhile, is reported to be around $75 million, according to Celebrity Net Worth.

So, how does that break down into a monthly payday?

According to court documents obtained by E! News and the Daily Mail, the individual income of Urban and Kidman was detailed in a Child Support Worksheet that forms part of the custody agreement for the pair's daughters.

This document listed their joint income at a whopping $200,000, breaking down as an even $100,000 each - again, much more than many Americans could hope to make in a year.

Urban's hefty income comes from his work as a singer-songwriter, musician, and composer, as well as through the money he makes while on tour.

Meanwhile, Kidman was named the highest paid actress in the world in 2024 after raking in an estimated $31 million thanks to her involvement in titles including Lioness, The Perfect Couple, Expats, Babygirl and A Family Affair.

According to the documents, neither Urban nor Kidman will be paying 'any amount and/or form of alimony or spousal support to the other', and they will not provide each other with child support.

Kidman has requested to be the 'primary residential parent' to the couple's daughters, with both parents having signed off on the plan that will see Sunday and Faith spending 306 days a year with Kidman, and 59 days with Urban.
