Kelly Clarkson was granted primary physical custody over her 2 minor children with estranged husband Brandon Blackstock on Monday.
The legal victory comes as People magazine reports that the music manager is requesting $436,000 a month in spousal support and child support from Kelly.
Kelly, 38, filed for divorce from Blackstock in June after 7 years of marriage. They share daughter, River Rose, 6, and son, Remington Alexander, 4. Blackstock also has two children from a previous marriage: Seth, far left, and Savannah, 2nd from left.
A source tells People that Blackstock, 43, has been "unreasonable" in his requests for support and attorney's fees from the 2002 American Idol winner.
"Kelly's offered to pay for all the kids' expenses, but Brandon seems to think he is entitled to and needs $301,000 in spousal support and $135,000 in child support per month," said the source.
Blackstock claims he needs $5.2 million a year to continue living the life of luxury that he was accustomed to while married to Kelly.
The source said, "Additionally, he's already asked for $2 million for attorney fees when he's the one driving up the cost of the divorce with seven attorneys just representing him alone.
Blackstock and Kelly are pictured during happier times at the UglyDolls premiere on April 27, 2019.
