Carrie Underwood is donating $1 million from her current tour to the American Red Cross to assist in disaster relief efforts in Oklahoma. The contribution comes from concert proceeds during her Blown Away tour which wrapped up Thursday night (May 23) in Abbottsford, British Columbia.

"I have watched the devastation in my home state of Oklahoma over the past several days with great sadness," Underwood said. "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."

Monday's twister that hit Moore, Okla., killed 24 people, destroyed an estimated 13,000 homes and caused an estimated $2 billion in damage.

Underwood established a charitable fund when the tour began in 2012. In November, she donated profits from a concert in Atlantic City, N.J., to relief efforts after Hurricane Sandy struck New Jersey. Funds from the latest donation will be used to pay for disaster relief initiatives in Oklahoma and other states.
