The star-studded show is to be taped April 2 at the MGM Grand Garden Arena. It will be broadcast April 13 on CBS.
The event will feature country music collaborations with Richie from his upcoming album, "Tuskegee," along with solo performances.
"It has been so rewarding to have my songs embraced by country music artists," Richie said in a statement Monday.
"It's the ultimate compliment to have country artists record and perform songs that I've written. I've always felt right at home in country because I was raised just down the road from Nashville in Tuskegee, Ala., where I was immersed in country, R&B, gospel and classical music."
