Their presence serves to raise awareness about the homelessness crisis, said Herb Smith, the mission's president.
"Homelessness is not just a Skid Row issue. It's a community issue and when celebrities, talent are able to let their face and their celebrity to the cause, it helps everyone understand the need," he said.
L.A. Police Chief Micheal Moore was also expected to participate.
After the Christmas feast, toys and goodies were distributed by Santa and his helpers.
