Underwood is using grants she would receive as the reigning Academy of Country Music entertainer of the year for the fund. Lifting Lives is donating money from the taping of "ACM Presents: Brooks & Dunn -- The Last Rodeo" tribute special that airs Sunday on CBS.
Starting Thursday, people can donate $10 by texting "ACM" to 501051. Underwood has taped a public service announcement that will air during the Brooks & Dunn special.
