During a tornado relief concert in Durant Oklahoma recently attendees at the concert got a real special surprise!

Kelly Clarkson joined Blake Shelton on stage for a duet of her #1 hit that she had with Jason Aldean "Don't You Want To Stay". A fan at the show captured the duet and the video surfaced on youtube recently. Blake holds his own with Kelly and for the fans it was a special treat!

Over $500,000 was raised during the two night benefit show with Kelly Clarkson, Blake Shelton & Reba on the bill.
