Sean Penn, Charlize Theron and Woody Harrelson got into the festive spirit on Friday (13Dec13) by attending a holiday party thrown by Family Guy creator Seth Macfarlane at his California home.

The Ted filmmaker turned his pad into a winder wonderland and invited his famous friends, including Molly Simms, Nick and Vanessa Lachey, Brittany Snow, Aziz Ansari, Paris Hilton and Emile Hirsch, to dance the night away as they enjoyed a lavish spread of food.
