Getting charitable over the weekend, Hilary Duff was all smiles as she stepped out for a fundraising event in Santa Monica, CA on Saturday (December 10).

Clad in a colorful yellow top, the expecting "Cheaper By the Dozen" star joined a group of young children at the local ice rink during the "Danskin: Move For Change" festivities.

Also receiving a $10,000 check for her Blessings In a Backpack charity initiative, Duff tweeted prior to the appearance, "Heading to ICE in Santa Monica for danskin move for a change initiative! Cant wait to see all the cute little kids ice skating :)"

Having just returned to the States following a trip to Canada, Hilary wrote last night, "Went to Toronto the other day and watched the whole last season of shameless on the plane!best show!full on obsession! anyone?anyone?"
