The revelation that Nicole Kidman and Keith Urban are divorcing after nearly two decades together shocked many. The couple, who have two teenage children, seemed to be as solid a celebrity couple as any, and more so than many. While there are few details regarding what, if anything, specifically happened to cause the split, the couple now has to navigate a celebrity divorce.

As happens when any major stars split, there is a lot of property and a lot of money that needs to be separated between the two parties. A decent chunk of that money could be coming Keith Urban’s way, due to a stipulation in the couple’s prenuptial agreement that’s being called the “cocaine clause.”
