Underwood, who has received five CMA awards so far in her career, says she's again looking forward to sharing the stage with her good friend. "I'm so honored to be asked back with my friend, Brad. The creative process of getting ready for the show is a blast, and I look forward to sharing country music's biggest night with all the fans!"
Paisley, the current CMA Entertainer of the Year, added: "I love working with Carrie, she's a class act and a complete balance to my non-class act. I'll try my best to not mess it up."
The 45th Annual Country Music Awards show is set to air live from Nashville November 9 on ABC.
