In a recent development to the ongoing legal battle between Kelly Clarkson and her ex-husband Brandon Blackstock, the Grammy-winning singer has filed new documents claiming that Blackstock may owe her a substantial amount of money beyond the $2.6 million previously ruled by a California labor commissioner.

Clarkson, 41, filed the documents on Monday in Los Angeles, alleging that Blackstock has violated state labor rules dating back to 2007. This includes the period when she entered into an oral agreement with Starstruck Management, a company founded by Blackstock's father, Narvel Blackstock, in 1988. The new documents, obtained by PEOPLE, seek a comprehensive financial accounting from Starstruck, demanding details of all monies received in connection with Clarkson's personal services, including commissions, fees, profits, advances, and producing fees.

The initial ruling in November 2020 concluded that Blackstock had unlawfully procured Clarkson's work, violating California's Talent Agencies Act. The act prohibits managers from securing employment for artists without the involvement of a licensed agent. The ruling revealed that Blackstock and his company, Starstruck Management Group, had breached the act on four separate occasions, including during Clarkson's role as a coach on The Voice starting in 2018.

Blackstock, 47, who managed Clarkson from 2017 to 2020, the same year their seven-year marriage ended, submitted an appeal to the decision in December. The hearing for the appeal is set to take place in August.

This legal confrontation began in September 2020 when Starstruck sued Clarkson for unpaid commissions amounting to over $1.4 million. In response, Clarkson counter-sued, accusing Starstruck, Brandon Blackstock, and Narvel Blackstock of Talent Agencies Act violations.

Despite the ongoing legal battle, Clarkson's divorce from Blackstock was finalized in 2022. As part of the settlement, Clarkson was ordered to make a one-time payment of just over $1.3 million to her ex-husband, along with monthly child support payments amounting to $45,601.

The proceedings are expected to shed light on the financial intricacies of Clarkson's professional career and the management practices of Starstruck Management Group. With the August hearing approaching, the outcome of the appeal will play a crucial role in determining the final resolution of this legal dispute.

It remains to be seen whether these new documents filed by Clarkson will have an impact on the amount of damages owed by Blackstock, as the pursuit for a complete financial accounting continues to unfold.
