The Outer Banks actor described it as a "great gift" to be able to act alongside Panettiere in Nashville.

He posted on Instagram: "She was, of course, extraordinarily talented, infusing her larger-than-life character with all the heart, charisma, humour, whip-smart intelligence, and flat-out magic that were, alongside whatever troubles and pain she carried, a part of her own personal palette.

"What a great gift it was to act with her, sing with her, and to just be her friend."
