Sharing a message about the fires at the time, Cyrus said: "I am one of the lucky ones. My animals and LOVE OF MY LIFE made it out safely and that's all that matters right now.
"My house no longer stands but the memories shared with family and friends stand strong. I am grateful for all I have left.
"Sending so much love and gratitude to the firefighters and LA country Sheriff's department...I love you more than ever."
