The raging California fire that's ravaged the swanky Calabasas neighborhood had Khloé Kardashian and half-sisters Kendall and Kylie Jenner frightened their homes might become part of the destruction.

All three took to Snapchat Saturday with clips of the billowing smoke after the blaze broke out, with Kylie, 18, wondering, "Am I going to have to evacuate?"

Khloé, 31, reassured her (also over Snapchat) that she'd be okay. "No, Kylie, you won't have to evacuate, because it's closer to my house than yours, sadly, so let's pray nobody has to evacuate," she said.

The fire broke out after a pickup truck crashed into a utility pole. About 5,000 people did have to leave their homes after flames spread out over more than 500 acres. Three buildings were damaged or destroyed but thankfully there were no reported injuries, Los Angeles County Fire Department officials said.

By Sunday morning, the blaze was 30 percent contained. We're wishing everyone in the area well and hoping they stay safe!
