That's Dierks Bentley's own flesh and blood starring with him in the video for his new song, "Living."

Dierks told me that doing the video with Knox, 5, was "as fun to shoot as it looks."

This appears to be the first time Knox has shared the spotlight with Dad. Older sister Evie has seen some of the stage with her father - singing and er, flossing, as seen here.
