Oklahoma native Blake Shelton is rushing to the aid of the people of his home state by putting together the Healing in the Heartland benefit concert. The show, which is set to air live on NBC on Wednesday night (May 29), has added more stars to an already star-studded lineup.

Country stars Luke Bryan, Rascal Flatts and have been added to the show, as well as Ryan Tedder from the pop band OneRepublic. Both Tedder and Joe Don Rooney from Rascal Flatts have strong ties to Oklahoma.

'Healing in the Heartland' will take place at Chesapeake Energy Arena in Oklahoma City on NBC on Wednesday night at 7:00pm CT, and will also air on CMT, Style, G4, E! and Bravo. The show will take on a telethon format, and viewers will be asked to make donations as they're watching.The new additions to the concert will join several other stars who had previously jumped on board. Miranda Lambert, Reba McEntire and Vince Gill are all in for the benefit concert which sold out in only 30 seconds.

The concert will benefit victims of the deadly tornado in Moore, Oklahoma tornado May 20thm, and the money raised from the event will go to the United Way of Central Oklahoma May Tornado Relief Fund.
