Trace Adkins told the world he had been sober for 12 years until he fell off the wagon on a cruise ship gig he was headlining this week. I think his definition would differ from that of the rest of the world, but whatever. What makes this one of the more interesting rehab visits in awhile is that while Trace was on a cruise ship to perform he ended up getting into a fight with a fan. Not just any fan, but a guy who makes a living as an impersonator of Trace. Trace has met the fan before with nothing happening but this time on the cruise was different. Probably because the cruise ship was filled with Trace Adkins fans so they might have given the impersonator a little more attention than Trace liked so they got into a fight. As soon as the ship docked Trace went to rehab. Sounds like the fight Demi Lovato got into with her backup dancer before Demi checked into rehab. At the time she made it sound like her eating disorder caused her to throw a punch. A few years later she admitted the truth. Trace might never admit the truth but this cruise ship ride wasn't the first slip. More like the last straw.
