Entertainment Music Country Trace Adkins Performs Visibly Drunk at a New Jersey Concert: 'Everyone Is Pulling for Him,' Says Source The singer donates his performance fee to charity after taking the stage intoxicated By Danielle Anderson Published on July 15, 2016 06:30 PM Share Tweet Pin Email Photo: Erik Pendzich/REX/Shutterstock Those close to Trace Adkins are rallying around him after he took the stage intoxicated during a show in New Jersey on Wednesday. The singer slurred his words and struggled to work through his set at radio station Rockin' Country Thunder 106's Guys with Guitars Under the Stars concert in Seaside Heights, New Jersey. "Very sad," posted concertgoer Jill Zangara Hartobey of South River on the Country Thunder Facebook page. "Felt so bad leaving but too hard to watch. Such a hard disease to conquer. Hope he can make it work." "This illness is an everyday fight," a source close to Adkins tells PEOPLE. "Trace is a fighter and everyone is pulling for him." Adkins, 54, has since agreed to donate his performance fee from the concert, which also featured David Nail and Love and Theft, to St. Jude Children's Research Hospital.

He last completed a rehab program in 2014 after an incident where he headlined a country cruise to Jamaica and reportedly got into an argument with a Trace Adkins impersonator who was singing karaoke in a bar on the ship. Adkins also completed a 28-day rehab stay in 2001 and has been open about his struggle. "I was getting to the point where I was poisoning myself [by drinking so much]," he revealed in a 2009 GAC special. His family, including third wife Rhonda and his daughters, staged an intervention at the time. "I wish for anybody out there to never have to go through one of those intervention things where you sit down there and people start telling you what you're doing to them," he admitted. "You're so weak that it's come to this. Man, I hated myself at that moment." Adkins and Rhonda split in 2014.
