AceShowbiz - Country star Kane Brown is hitting back at a breach of contract lawsuit filed against him by producer Polow Da Don.

The "What Ifs" star was previously sued by Polow, real name Jamal Jones, amid allegations suggesting Brown had broken the terms of a recording agreement they had signed in 2015.

According to Polow, he offered to produce a project for Brown via his company Zone 4, which involved the singer releasing one album for the firm, and granting executives 50 per cent of its royalties, as well as 25 per cent of all profits made from live shows, collaborations, sponsorship deals, and other ventures.

However, Brown and his representatives subsequently struck a separate deal with Sony Music Entertainment bosses, who own RCA Nashville, and signed with Universal Music Publishing Group, too.

Polow, who produced Kane's breakout single "Used to Love You Sober", claims Brown's lawyer abruptly terminated their Zone 4 contract, and the country hitmaker therefore still owes him a cut of earnings and advances received for both label agreements.

However, Kane has since filed a countersuit, accusing Polow of handing him a fraudulent deal by failing to disclose a business agreement the producer had in place with Epic Records - effectively tying Brown to the label without his knowledge.

"Mr. Brown would not have entered the 2015 agreement with Zone 4 had he known that Zone 4 was contractually prohibited by operation of the Secret 2013 Epic/Sony Deal from shopping his recording to any record labels other than Epic/Sony," the singer's lawyers state, according to court papers obtained by The Tennessean.

They go on to slam Polow for having "fraudulently induced Mr. Brown into signing a lopsided recording agreement in 2015 and repeatedly misled Mr. Brown and others to protect it."

The contract is said to have cost Brown "millions and drastically limited his earning potential".

He is seeking to have Polow's lawsuit dismissed, while he is also requesting to be reimbursed for "any and all proceeds and revenue" from the Zone 4 deal.

The case is ongoing.
