Piece by Piece Kelly Clarkson is scoring small victories in her legal battle against Brandon Blackstock.The “American Idol” alum’s ex husband was ordered to return the millions he allegedly overcharged the singer while booking gigs on her behalf, according to legal documents obtained by TMZ.A California labor commissioner ruled that Blackstock, 46, “crossed the line” when he booked jobs for the 41-year-old talk show host as her manager, a duty that is technically usually reserved for agents, and must hand over $2,641,374 back to Clarkson.In December 2020, Clarkson alleged that Blackstock acted fraudulently as her manager. But Blackstock denied defrauding his estranged wife out of millions at the time.The gigs and completed contracts for which Blackstock took home a hefty salary include booking Clarkson as a judge on “The Voice,” in ads for Norwegian Cruise Line and Wayfair, and hosting the Billboard Music Awards.
