Brittany Aldean vows to 'live like Charlie' after attending massive memorial service for Turning Point founder

Brittany Aldean felt a range of emotions while attending Charlie Kirk's memorial service in Arizona on Sunday.

Brittany, 37, joined husband Jason Aldean and nearly 100,000 others at State Farm Stadium to mourn the loss of the Turning Point founder, who was shot and killed while speaking outside of Utah Valley University on Sept. 10.

The former "American Idol" star admitted the day "was overwhelming," but that she was inspired by how Kirk "impacted people" as she detailed the service for her social media followers on Instagram.
