Shelton told reporters about the fundraising effort after Tuesday night's episode of "The Voice." Shelton, an Oklahoma native, paid tribute to the thousands affected by Sunday and Monday's tornadoes by performing an acoustic version of the hit "Over You" with wife Miranda Lambert.
He said the benefit would be held soon in nearby Oklahoma City.
At least 24 people, including nine schoolchildren, were killed Monday afternoon in Moore, Okla., when an F-5 tornado with 200 mph winds touched down for 40 minutes and destroyed entire neighborhoods.
Toby Keith, a native of Moore, also is planning a benefit. His sister's house was hit by the tornado.
More details about both fundraising efforts will be released later.
