After kicking off the show with a performance, Adkins revealed that the network said he needed to have a co-host for his second time hosting the awards show.
"They felt I didn't follow the rules too well, so this year they're giving me a co-host to keep me in line," Adkins told the crowd. "Make some noise for my opponent tonight: Kristin Chenoweth."
The Glee star then entered the MGM Grand in Las Vegas clad in a bright red robe and boxing gloves, circling Adkins and trying to punch him.
"Watch the below the belt stuff, there," Adkins told Chenoweth.
"You get ready to behave yourself," Chenoweth responded. She then removed her boxing gloves and handed them to Adkins.
"I want to get my hands on country's sexiest man," Chenoweth told the crowd to great applause.
Adkins lost his home in a fire in June this year, although he and his family managed to escape unharmed.
