Blake Shelton Planning Oklahoma Benefit Concert: Which Other Celebs Are Helping Out?

Celebrities can tweet condolences all they want, but Blake Shelton is putting his money (and his guitar) where his mouth is when it comes to those affected by the Oklahoma tornado.

"The Voice" judge opened Tuesday night's show by performing an acoustic version of "Over You" alongside wife Miranda Lambert while donation information for The Red Cross was presented on screen. The couple originally co-wrote the song in honor of Blake’s older brother, who passed away when he was a teenager.

Following Shelton's touching tribute, the Oklahoma native revealed he and NBC have started to organize a benefit concert for the victims of the tornado that killed at least 24 people, nine being children.

"We'll know more about it in the next 24 hours," Shelton told Billboard. "I'm hoping it will raise a lot of money. Obviously, it will be televised and will happen really quickly."

Shelton grew up about 75 miles south of where the tornado struck in Moore, Oklahoma, on May 20.

It's very likely that Shelton will recruit a slew of high-powered performers for his benefit concert. "I can call in some pretty big favors," Shelton said. "The Voice" judges, both ex and current, which include Cee Lo Green, Christina Aguilera, Adam Levine, Shakira, and Usher would seem to be likely candidates. Plus, we wouldn't be surprised if Shelton's wife, Lambert, and close pals Kelly Clarkson and Sheryl Crow joined too.

Shelton certainly isn't the only star rushing to help the tornado victims.

Oklahoma City Thunder all-star forward Kevin Durant donated $1 million to The Red Cross, which the team pledged to match along with the NBA and National Basketball Players Association.

Dodger outfielder Matt Kemp, who is from Oklahoma City, also got in on the action:

Kristen Bell also tweeted:

Actor David Spade also donated to the Red Cross, giving $200,000 for relief efforts.
