Blake Shelton Planning Tornado Relief Benefit

"The Voice" coach said there will be more details to come in the next 24 hours

A little help may be on the way for victims of the Oklahoma tornadoes: Blake Shelton says he is putting together a benefit.

Shelton said after Tuesday night's "Voice" taping that he and NBC are organizing the event, though NBC could not confirm that for TheWrap on Wednesday.

"We are actually putting together a fundraiser right now with NBC," Shelton told CNN. "We'll have more details within the next 24 hours, but definitely something with NBC that is going to happen real fast, and hopefully raise a lot of money."

Shelton talked to reporters soon after he and his wife, Miranda Lambert, sang their hit "Over You," which they wrote as a tribute to Shelton's brother, who died when Shelton was a teenager.

Shelton's fellow coach on "The Voice," Usher, said he hopes to be involved in the benefit.

"I have family in Oklahoma City," he told CNN. "My little sister, Ashira — her family is OK. Unfortunately, that is something that you can't — all you can do is put your best efforts forward, just let those who have been a part of this tragic reality, this natural disaster, know that we are thinking about them and care about them. I think that is 100 percent the effort."

At least 24 people, including 10 children, were killed when a tornado touched down Monday in Moore, a suburb of Oklahoma City.

NBC aired a concert for victims of Hurricane Sandy in November.

Other networks have not yet responded to inquirer about whether they are planning benefits or other help for tornado victims. ABC-Disney, CBS and Fox all gave more than $1 million to Sandy relief.
