Watch: Marie Osmond Works Miracles Serving Ice Cream

ET was there as Marie Osmond served up delicious ice-cream treats while working behind the counter at Dairy Queen on Thursday -- all for a charitable cause.

As part of Miracle Treat Day, Marie and KIIS FM radio host JoJo Wright dished up tasty Blizzards to delighted DQ customers in order to help raise money for Children's Miracle Network, which Marie co-founded. A dollar or more from every Blizzard sold will be donated to local children's hospitals.

"The need is great and the cause is fantastic. It's charity at the highest level," Marie said.
