Rock is among the first guests announced exclusively to PEOPLE for the inaugural CMT Artists of the Year. The singer, who hosted the CMT Awards in June and performed "Born Free" on the CMA Awards in November, will present one of the trophies to the 2010 Artist of the Year winners: Lady Antebellum, Taylor Swift, Jason Aldean, Carrie Underwood and Zac Brown Band.
Martina McBride and Paramore’s Hayley Williams will share presenting duties with Rock. And during the 90-minute special, honorees will be treated to performances of their hits by just-confirmed artists Adele, Joe Perry of Aerosmith, Maroon 5 and Darius Rucker.
Song selections are hush-hush, but speculation is that Adele, the British two-time Grammy award winner might perform CMA Group of the Year Lady A's "Need You Now" since she has cited the trio as a creative influence on her new album 21, due out in February 2011.
Academy award winner Kevin Costner, who earned his hillbilly bone playing the Grand Ole Opry with his country-rock band Kevin Costner and Modern West, will host the show, CMT Artists of the Year, which airs Friday, Dec. 3 at 8 p.m. ET on CMT.
