Paisley is the reigning CMA entertainer of the year. Paisley and Underwood have won 19 CMA awards between them.
As Paisley notes in a news release announcing their return, they've achieved a comic chemistry over the years with Underwood's class balancing "my non-class act. I'll try my best to not mess it up."
The CMA Awards are the most-watched country awards show. More than 16 million viewers tuned in last year.
