Kellie Pickler will sing on Capitol Hill Wednesday afternoon to help honor grandparents who raise their grandchildren.
It's a deeply personal issue to Pickler, who was raised by her grandparents in North Carolina after her parents divorced and her mother left when the country star was only 2-years-old.
The Idol alum will perform her song "My Angel," written for her grandparents, Faye and Clyde Pickler, at the AARP's third National GrandRally. The event hopes to raise awareness of and support for "grandfamilies" like the Picklers.
"I know the struggles they face," said the singer, who has donated nearly $50,000 to the AARP's Grandparent Foundation.
