Kelly Clarkson is being sued by Starstruck Management Group, her longtime management company over alleged unpaid commissions.

Per reports, the suit alleges a breach of oral contract and seeks declaratory relief and accounting. It claims that Clarkson failed to pay millions in commissions for her work on ‘The Voice’ and ‘The Kelly Clarkson Show.’

According to the complaint, Clarkson had paid the firm $1.9 million earlier this year but still owes another $1.4 million. The suit also states that Clarkson will owe the group at least $5.4 million by the end of the year.

The complaint alleges that the terms between Clarkson and Starstruck Management Group were verbally negotiated and with no formal written agreement was made when the deal was struck in 2007.

The lawsuit was filed yesterday Tuesday, September 29th in Los Angeles Superior Court by Starstruck Management Group which is headed by Narvel Blackstock, father of Clarkson’s ex-husband, Brandon Blackstock. The two filed for divorce earlier this year.’

The official complaint states,

“Over the course of approximately 13 years, Starstruck developed Clarkson into a mega superstar. By way of example only, Starstruck was instrumental in helping Clarkson achieve success in terms of numerous hit albums, multiple Grammy wins and nominations, her role on popular television shows ‘The Voice’ and her talk show.

Despite Starstruck’s hard work and dedication, Clarkson has decided she is going to stop paying Starstruck for what is contractually owed.”
