California Gov. Gavin Newsom, who declared a state of emergency, urged residents to evacuate after he witnessed buildings destroyed by the blaze.

Evacuation orders were initially issued for one zone, but several more were quickly ordered to flee as firefighters worked to contain the blaze.

"Star Wars" actor Mark Hamill was among the thousands who evacuated Los Angeles. Other stars, including Paris Hilton, Billy Crystal, and Rainn Wilson have lost their LA homes.
