"I'm looking forward to cutting loose again with Kristin, who's quite the firecracker comedienne, while we also take viewers through an evening of great music and awards," Adkins said in a statement.
For her part, the 4' 11" Chenoweth is looking forward to seeing Adkins -- 6' 6" -- and his "big personality and even bigger boots" again.
"We had a blast last year and I plan to pull out all the stops to make sure everyone has a good time," she said.
