Blackstock’s partner, Brittney Marie Jones, who used to be his ex-wife Kelly Clarkson’s assistant, was allegedly at the service. It is unclear if Clarkson was in attendance. “Brittney, his family and his closest friends spent time at his home sharing memories of Brandon and remembering how much he meant to them,” the insider said.

A source alleges that Brittney Marie Jones’s now-ex-husband, Greg LaPoint, found out about her alleged affair with the music executive in the summer of 2023. “He got screwed over due to [Jones and Blackstock’s] fling starting during his marriage,” the insider claims.
