The music world is reeling after the sudden death of Brandon Blackstock, 48 — ex-husband of Kelly Clarkson and father to her two children, River Rose and Remington Alexander. At a private Nashville chapel yesterday, family, friends, and country music stars gathered to say goodbye. In the most emotional moment of the service, Kelly Clarkson and longtime friend Blake Shelton — who had introduced her to Blackstock years ago — performed a stripped-down acoustic version of “God Gave Me You”, the song played at their wedding. Kelly’s voice shook as she began the first verse, Blake quietly taking over for the second. Together, they harmonized through the chorus while her children sat in the front row, holding hands, tears rolling down their cheeks. “It wasn’t just a performance,” one attendee said. “It was a goodbye you could feel in every note.”
