Cara Delevingne, the British model and actress, has said her “heart is broken” after a fire destroyed her $7 million (£5.5 million) home in Los Angeles.

The 31-year-old, who is starring in Cabaret at the Kit Kat Club in London’s West End, posted a video of a fire engine and flashing lights online following reports and video footage showing her property in flames.

The Los Angeles Fire Department (LAFD) said there have been no reported injuries to civilians or firefighters following the blaze at the Studio City address and added that its cause remains under investigation.

In her Instagram story, Delevingne thanked the firefighters for helping to save her two cats, which she initially thought had perished in the blaze.

“My heart is broken today. I cannot believe it,” she said. “Life can change in a blink of an eye. So cherish what you have.”

She added: “Thank you from the bottom of my heart to all the firefighters and people that showed up to help...”

Alongside a picture of her cats, she wrote: “They are alive!! Thank you to the firefighters.”

A post on the LAFD website said: “Firefighters arrived to find a four-storey building with fire showing from the second floor.”

It took a team of 40 firefighters 21 minutes to extinguish the fire, it said.

“After firefighters entered the structure to eliminate the remainder of the flames, crews ventilated the building to remove any lingering smoke and conducted a search for any victims,” the statement continued.

“No reported injuries to civilians or firefighters. The cause of the fire is under investigation.”

Delevingne gave Architectural Digest a tour of her Los Angeles home, which she called her “adult playhouse”, in 2021.

It includes a ball pit, projector screen, trampolines and a pool.

Delevingne’s representatives have been approached for comment.
