The 30-year-old singer, who grew up in Muskogee, was left distraught after twisters swept through the region around Oklahoma City, leaving 24 people dead, including nine children.
Now she is aiding the relief effort in a big way by handing over a cheque to the Red Cross, reported Ace Showbiz.
A statement from Underwood read, "I have watched the devastation in my home state of Oklahoma over the past several days with great sadness. With the help of my fans who attended my concerts over the past year, we can offer the Red Cross a little extra help in comforting those affected by the recent tornados."
"Through the generosity of Carrie, the American Red Cross can quickly respond with shelter, food and comfort now, and with lasting help as they move toward recovery.
