The roof of the British-born model and actress’s Studio City residence, which is reputedly valued at $7 million (£5.5 million), collapsed on Friday morning due to smoke and flames.
At the moment, 31-year-old Delevingne is in the UK performing in the West End production of the musical Cabaret.
The celebrity sent three messages and a video to her Instagram Story on Friday.
“My heart is broken today,” she wrote with a photo of two cats with a broken heart emoji, which appeared to suggest the animals may have perished in the fire. It’s unbelievable to me. In an instant, life may drastically alter. Thus, value what you already have.”
