The Since You Been Gone singer is fresh off a victory after the judge ruled the couple's prenup would stay in place, which means Clarkson gets to keep the millions she made during their 7-year marriage.
Now, she reportedly wants to unload their Big Sky Country home.
Clarkson allegedly bought the ranch, meaning she owns it now and can do what she wants -- and she reportedly wants to sell. The only problem is her ex currently lives there.
As Radar reported, Blackstock -- who was once Clarkson and her good friend Blake Shelton's manager -- left the music business and is now working full-time as a ranch hand on the Montana property.
He desperately tried to fight Clarkson over their prenup. Blackstock pulls in $10,000 per month as opposed to his estranged wife, who brings in a whopping $1.5 million every month.
Earlier this month, it was revealed The Voice judge won't be paying a dime towards the Montana ranch after a judge sided with the singer, agreeing she's not on the hook for the massive property.
The judge ruled that Blackstock would be responsible for the $81,000 a month bill for the ranch.
Clarkson is already giving her ex a boatload of cash every month to the tune of $200,000, which breaks down to $150,000 in spousal support and $45,601 in child support.
She's also been handed the bill for their kid's pricey education. The judge ruled the Because of You singer will pay 70% of the tuition and other costs associated with their children's private school.
Clarkson isn't hurting for money though. The daytime host is reportedly taking over Ellen DeGeneres after she ends her final season -- so she's set.
The star celebrated her prenup victory by getting the hell out of Dodge and heading straight to Sin City.
Clarkson is currently living her best life in Las Vegas with her girlfriends, while her estranged husband might be scrambling for a new place to live.
