Reba McEntire and Blake Shelton raised $500,000 for victims of recent tornados in Oklahoma during two sold-out “Tornado Relief Concerts” at the Choctaw Events Center in Durant on May 25th and 26th. Kelly Clarkson made a surprise guest appearance at the May 26th show. Shelton and McEntire sang for more than two hours each night. The pair co-headlined the event, opening with a duet of “Oklahoma Swing.” A special mobile fundraising campaign has been set up with The mGive Foundation. Fans can text “OKGIVE” to 27722 to make a $10 donation. Checks can also be made out to the Tushka Disaster Relief Fund and mailed to: 101 SE 1st Street, Tushka, Oklahoma, 74525.
