Kelly Clarkson’s divorce from her husband of seven years Brandon Blackstock, who is the father to her two young children, has taken yet another nasty turn as she is claiming in new court documents that he acted fraudulently as her manager.

Court documents obtained by Page Six show that Clarkson, 38, is accusing members of her former management company Starstruck Management, specifically Brandon and his father Narvel, of fraud and “illegal services.” In the filings, Clarkson described her partnership with Starstruck as a “fraudulent and subterfuge device” for Starstruck’s “illegal services” as unlicensed agents.

This came after Narvel filed a lawsuit alleging that Clarkson owed Starstruck $1.4 million, and that she would continue to owe them based on whatever money she makes both from her eponymous talk show and from her work on “The Voice.” Clarkson fired back in her own filing by claiming that the Blackstocks were not licensed to act as agents in California, and that they hid that fact from her while simultaneously “demanding unconscionable fees,” “acting in conflict of interest” with her, and “giving false information and/or making false representations.”

The California’s Talent Agencies Act requires agents operating in the state to be licensed and bonded, and the former “American Idol” winner claims that Starstruck neither obtained the bond nor her written approval to act as her agent.

Clarkson and her lawyer Edwin McPherson claimed that “based on the wrongful acts and conduct of [Starstruck Management and the Blackstocks] … all agreements between the parties, should be declared void and unenforceable.”

They are fighting to permanently stop Clarkson’s payments to Starstruck, and to have her previous payments to the management firm paid back.

Earlier this month, Clarkson admitted that her divorce was “horrible.”

“I’m going through one right now. It’s horrible,” Clarkson said while opening up about her divorce proceedings on her talk show. “There are so many hard parts. The hardest for me is the kids. That’s the hardest for me. I think, as women especially, we’re trained… to take it all on, and you can deal with it, and you’re fine, but it’s your babies that you worry about.”
