Brandon Blackstock is being remembered by his brother. The 48-year-old talent manager passed away this week after a three-year battle with cancer. He will be dearly missed, especially by Shelby Blackstock. His younger brother took to Instagram to honor him in an emotional post. The race car driver shared a bunch of photos of Brandon, including one of the whole family smiling at the camera alongside former stepmom Reba McEntire. He wrote in the caption: "Words cannot begin to capture the tremendous loss our family has endured. Yesterday, we lost a brother, a father, a grandfather, and a son.
