Cara Delevingne's Mother and father Reveal Reason for Home Hearth, Say She's Devastated

Cara Delevingne‘s tragic house fire may have been electrical in origin … at least that’s what her mom and dad are saying — who are out in the UK to support their daughter’s play.

The model’s parents, Charles and Pandora, got interviewed by a photog Friday in London — where it seems the whole family’s in town as Cara performs there at the Playhouse Theatre. They were asked if they knew how the fire started, and they said they did.

Check it out … Charles says a rogue powerline may be to blame after a “very windy” night in Southern California. He also says that it was an electrical fire that got out of control.

FWIW … we’re hearing from our law enforcement sources that an official cause still hasn’t been attributed just yet — and officials are still in the early stages of the investigation.

BTW, despite reports suggesting this being investigated as arson — our sources tell us that’s not entirely accurate. While an arson unit is in the mix as they look into this — we’re told arson is not being seriously suspected. It’s SOP to have arson looked into for a fire like this.

We broke the story … Cara’s L.A.-area home caught ablaze in the early hours Friday — prompting a massive turnout from the fire department, part of which was caught on video.
