Blake Shelton is just one of the high profile headliners who will participate Wednesday during NBC's 'Healing in the Heartland' benefit.
The live telethon event, taking place at the Chesapeake Energy Arena in Oklahoma City, will air May 29, at 9 p.m. EDT, as well as cable networks Style, G4, Bravo, E! and CMT.
Joining the Oklahoma native and coach of 'The Voice' will be country entertainers Miranda Lambert, Reba McEntire and Vince Gill.
Funds raised will be earmarked for the United Way of Central Oklahoma May Tornadoes Relief Fund.
Shelton said, "Everyone has their way to help, and mine as an entertainer is to perform to help raise money and awareness for this tragedy. This is why I want to do this special and especially hold it in Oklahoma City, which is near ground zero."
Fellow Oklahoman Carrie Underwood donated $1 million to the American Red Cross.
The benefit will aid those affected by the powerful EF5 tornado, with 200 mph winds, that destroyed Moore, Oklahoma on May 20, killing 24 people, including 10 children in an elementary school.
