During the seven years that Brandon and Kelly were married, he also managed her professional career. Blackstock and Clarkson ended their marriage in June 2020, and the split was finalized in March of 2022. But away from their divorce proceedings, Brandon and Kelly have also been embroiled in a legal dispute about his time representing her as a manager. Kelly has accused her ex of unlawfully securing her contracts for The Voice, The Kelly Clarkson Show, Norwegian Cruise Line (NCL), Wayfair, and the Billboard Music Awards, and took fees in return for the deals. A new ruling has found that Brandon overstepped in his role as a manager in four of these five instances, because only talent agents can make deals on behalf of their clients — not managers. He took a total of $2,641,374 in commission for the four previously business deals, which he now must pay back to Clarkson. Blackstock is planning to appeal the ruling. Clarkson was granted primary physical custody of their two children, daughter River Rose and son Remington Alexander.
