Four months after a California labor commissioner ruled thatKelly Clarkson’s ex-husband Brandon Blackstockowed her $2.6 million in past commissionsfor overstepping his legal limits as her manager, the singer has filed new documents claiming he may actually owe her much more.

Clarkson, 41, filed documents in Los Angeles on Monday saying Blackstock has actually been violating state labor rules since 2007, when she entered into an oral agreement with Starstruck Management, the company his fatherNarvel Blackstockfounded in 1988.

Attorneys for Blackstock did not immediately respond to PEOPLE’s request for comment.

Blackstock, 47,served as Clarkson’s managerfrom 2017 to 2020, the same year she filed for divorce after seven years of marriage. In November, the labor commissioner said he’d “unlawfully procured her work” in a violation of California’s Talent Agencies Act.

Under the act, managers cannot procure or try to procure employment for artists unless they act in conjunction with a licensed agent, and the ruling said Blackstock and his Starstruck Management Group violated the act in four different instances, including Clarkson’s stint as a coach onThe Voicestarting in 2018.

Blackstock — with whom the “Mine” singer shares daughter River, 9, and son Remy, 7 — filed to appeal the decision in December, and a hearing is set for August.

The filings began in September 2020, when Starstruck sued Clarkson, claiming she owed over $1.4 million in unpaid commissions. In response, she filed documents accusing Starstruck, Blackstock and Narvel (who was previously married toReba McEntire) of violating the Talent Agencies Act.

Clarkson’s divorce from Blackstock was settled in 2022, and she was ordered to pay her ex-husband a one-time payment of just over $1.3 million, as well as a monthly child support payment of $45,601.

“I didn’t see it other than: This is my outlet. I’m a let-go person; I don’t hold grudges. So it was really delving into what happened in my life and why—and what am I going to do about it?” shetold PEOPLE in January.
