Kelly Clarkson let out a scream on the set of "The Voice" when she received word that a judge upheld her ironclad prenuptial agreement.

The 39-year-old mom-of-two had been ordered to pay her ex-husband, Brandon Blackstock, $195,000 -per-month in temporary spousal and child support.

But the same judge fully upheld Kelly's prenup with Blackstock in their highly contentious divorce win, TMZ reported on Thursday.

The legal victory comes as People magazine reports that Brandon requested $436,000 a month in spousal support and child support from Kelly.

Kelly was awarded primary custody of their children, Remington and River Rose, because Blackstock lives on their farm in Montana, Page Six reports.

Blackstock has two children from a previous relationship.

Kelly will likely have to pay child support for Remington and River Rose, which will cost her $50,000 per month. But that's a drop in the bucket for her.

Court docs lists the singer/TV personalty's monthly income at over $1.5 million.
