It's been a tough year for Adkins, a former "Celebrity Apprentice" winner. In January he entered alcohol rehab following a run-in with a Trace Adkins impersonator while on the Country Cruising cruise. 

He left rehab in February to be with his ailing father, who died days later.

Adkins' country hits include the No. 1s "(This Ain't) Not Thinkin' Thing," "Ladies Love Country Boys," "You're Gonna Miss This" and "Hillbilly Bone."
