Brandon Blackstock Death: Shelby Blackstock Details “Void” One Year Later

Brandon Blackstock‘s brother is honoring him one year after his death.

Shelby Blackstock penned a touching tribute to the talent manager—who shared daughter River, 12, and son Remy, 10, with ex-wife Kelly Clarkson—on the first anniversary of his death following a private battle with cancer.

“It’s been one year since we lost you… a void that can never be filled,” Shelby wrote on Instagram Aug. 7. “It still doesn’t feel real. Sometimes it feels like we’re all just busy and overdue for a catch-up call. Then reality hits all over again. It’s a painful reminder every single day.”

“A lot has happened this past year,” the 36-year-old, whose wife Marissa Blackstock is pregnant with their first baby, continued. “As I’m getting ready to welcome my first son into the world, I’ve found myself thinking about what shaped me growing up. It truly took an army, but somehow it always came back to you.”

Shelby—the son of Reba McEntire and Narvel Blackstock—went on to reflect on their childhood together, and the strong sibling bond they shared. (Brandon and his two sisters are from Narvel’s marriage to Elisa Gayle Ritter.)
