The 34-year-old mom, who shares her eight-month-old daughter with Tristan Thompson, expressed the devastation she felt and thanked those who have been helping to control the blaze.
"Pray for Calabasas", she wrote on her Stories.
Two wildfires raging west of Los Angeles have forced thousands of people to leave their homes.
The City of Calabasas Twitter account wrote that they were evacuating everyone from the area and those surrounding, such as Hidden Hills and Aguora Hills.
The gossip website also said Caitlin Jenner's home that sat on a ridge overlooking Malibu beach had been destroyed.
"They're evacuating everyone right now from all of our homes", she said in the video as she watched on from her vehicle. "And unfortunately it's becoming more and more common here in California", actress Natalie Portman said Friday night in Hollywood at an American Film Institute Fest premiere of her film "Vox Lux".
While news reports have confirmed that numerous homes in a neighborhood in Calabasas have been destroyed, it's unclear whether the FaZe House is among those.

"Evacuated last night. Bleak House and the collection may be endangered but the gift of life remains", del Toro, director of Oscar best picture victor "The Shape of Water", tweeted on Friday.
The Malibu area is also home to dozens of filming locations. Cher tweeted that her friends' houses had been burned, adding that she could not "bear the thought of there being no Malibu".
Rainn Wilson, former star of The Office, singer Melissa Etheridge, and Roma Downey, the wife of The Apprentice producer Mark Burnett, all said they had scrambled to evacuate at short notice.
