Hilary Duff gave up her Saturday (27Aug11) to volunteer at a charity event helping the homeless in Los Angeles.
Duff, who is expecting her first baby with husband Mike Comrie, and her sister Haylie headed to the L.A. Mission's 75th annual end of the summer block party to offer their services.
The siblings donned matching red aprons as they helped hand out supplies to those in need.
In a post on her Twitter.com page before the event, Duff wrote, "Excited to head downtown to the la mission event today with @HaylieK such a great cause! We will be handing out backpacks (with) school supplies!"
