Rogers, who is retiring from touring, says his final performance with Parton will be part of an all-star farewell show to be held at Nashville's Bridgestone Arena on Oct.
Other performers for the farewell show are Little Big Town, Flaming Lips, Idina Menzel, Elle King, Jamey Johnson and Alison Krauss, with more names to be announced.
Rogers, 78, said it's been more than a decade since he performed with Parton for a CMT special.
"We both feel that comfort." "Performing with Kenny for the last time ever on October 25th is going to be emotional for both of us, but it's also going to be very special," Parton said in a statement.
"Even though Kenny may be retiring, as he fades from the stage, our love for each other will never fade away." The actor, singer and photographer with hits like "The Gambler," ''Lady" and "Lucille," announced in 2015 he would do a final farewell tour before retiring to spend more time with his family.
