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

The full statement read: "Unfortunately, Kelly Clarkson will be unable to appear at Band Together Texas as planned, due to personal circumstances. We send out love to Kelly and her family." Clarkson was slated to appear at the event at the Moody Center in Austin to help raise funds for the Community Foundation of Texas Hill Country and the Central Texas Community Foundation in support of Texans who were affected by July's deadly flooding.
