Singer Kelly Clarkson has to hand over a tenth of her income to her ex Brandon Blackstock during the settlement of her divorce.

In addition to that $150,000 a month, she also has to transfer about $50,000 a month for the living expenses of the couple's two children.

Clarkson and Blackstock announced last year that they are separating after seven years of marriage.

They have seven-year-old daughter River and five-year-old son Remington.

According to

The Blast

, which holds the court papers, Blackstock has indicated that he wants to make a career move and run the couple's ranch full-time.

He previously worked at his father's Hollywood agency and was the agent of, among others, Blake Shelton.

Clarkson would also have to pay Blackstock's now considerably increased attorney fees.

It would be more than a million dollars.

The alimony amounts that have now been determined only apply to the period in which the divorce is being settled.

A final amount will be determined later.
