Country singer Trace Adkins has reportedly checked into rehab to seek treatment for his alcoholism.

Adkins who had been sober for over a decade had started undergoing in-patient treatment back in December 2011. A representative of Adkins reportedly confirmed that “he entered a treatment facility after a setback in his battle with alcoholism.”  

The news of Adkins' latest rehab stint came shortly after reports of his altercation with an impersonator on a cruise ship.

According to reports, Adkins was celebrating his 52nd birthday on the Norwegian Pearl en route to the Caribbean, with some of his friends. He was supposed to perform in the ship’s main theater for seven days. The stops included Ocho Rios, Jamaica, Cozumel, Mexico and Grand Cayman.

On the ship, Adkins got into a fight with an impersonator who was singing in a karaoke bar, and the reason for the altercation is not known so far. Reportedly, he left the cruise ship in Jamaica before heading for rehab.

Adkins was supposed to perform along with other country singers, Montgomery Gentry and Wynonna, but his performances on the ship had to be cancelled.

The star has always been very open about his problems with alcohol. In 2011, Adkins credited his manager for saving his life, saying:

“If you’ve ever been through one of those things, it’s the most humiliating experience you’ll ever have. To hear people you respect and love sit there and tell you the kind of pain you’ve been causing them… and yeah, I’m an alcoholic,” he told The Hollywood Reporter at the time.
