The 17-year-old singer-actress will give $200,000 to the American Red Cross and $50,000 to USA Harvest, which is supplying food to shelters, according to a statement released Thursday by publicist Cece Yorke. The latter donation will amount to more than 300,000 cans of food being provided to victims.
Duff encouraged fans to bring canned food donations to her concerts and to give money to charities.
"It's heartbreaking to see the devastation on TV. People are missing family members, and they have absolutely nothing left, not even food and water," she said in the statement.
Duff's screen credits include "The Lizzie McGuire Movie," "Cheaper by the Dozen" and "A Cinderella Story."
