Kelly Clarkson delivers a harsh public message to ex-husband Brandon Blackstock over a family legal battle.

Kelly Clarkson appeared to openly criticize her ex-husband Brandon Blackstock during an opening episode of The Kelly Clarkson Show.

The singer, embroiled in a legal battle with her ex-father-in-law, made some telling lyric changes during her version of Gayle’s song ‘abcdefu,’ which many fans assumed was directed at Brandon, their high-profile divorce, and his father, Narvel.

Kelly shouted out as she began her Kellyoke performance at the beginning of the program, “F you and your dad and the fact that you got half and my broken heart, turn that [****] into art.”
