Thousands flee huge wildfire as it bears down on upmarket LA suburb that's home to stars including Kim, Kanye and Kylie Jenner

Thousands of people have been forced to flee their homes and celebrities have been sharing pictures of billowing smoke as a wildfire tears through southern California.

Kim Kardashian and Kanye West left their Calabasas home on Friday just before a third-alarm brush fire sparked up on Saturday in the area and Kylie Jenner shared photos of smoke on social media.

As that fire started three others broke out in southern California, NBC 4 reported, burning 200 acres of land and threatening 3,000 homes.

'Three thousand homes are evacuated, which is about 5,000 people,' Tony Coroalles, city manager of Calabasas, told CNN.

The fire forced mandatory evacuations in the Highlands, Eddingham and Adamsville neighborhoods, fire officials said.

But as night fell on the area and temperatures cooled, it was reported about 15 per cent of the fire had been contained.
