Camille Grammer Meyer of The Real Housewives of Beverly Hills also lost her home in Malibu, her publicist confirmed to the Associated Press.
Meyer’s publicist Howard Bragman said she is grateful to have safely evacuated with her family and is appreciative of the firefighters who have risked their lives fighting the blaze and is grateful for the love and concern shown to her.

“This place. I got married there. But before that, it’s the place @chriscortazzo let me stay in after my dad passed away. It’s the place I felt my dad with me. It’s gone. Fire has taken it away. I’m devastated by all that’s happening. My heart is ripped apart,” she wrote.
The fire also destroyed the historic Paramount Ranch where HBO’s Westworld was filmed.
An HBO spokesperson told Variety that the series wasn’t in production.
“As the area has been evacuated, we do not yet know the extent of the damage to any structures remaining there,” the spokesperson said. “Most importantly, our thoughts go out to all those affected by these horrible fires.”
Lady Gaga was also forced to evacuate her house.
“I am thinking so deeply for everyone who is suffering today from these abominable fires & grieving the loss of their homes or loved ones,” Lady Gaga tweeted. “I’m sitting here with many of you wondering if my home will burst into flames.

Alyssa Milano said her home was “in jeopardy.”
Horses are finally safe. My children are safe. My home is in jeopardy but … everything with a heartbeat is safe. Thank you all for your concern. To those who insisted on still being hurtful because our political affiliation is different, you are what is wrong with the country,” she tweeted.
U.S. President Donald Trump has blamed the wildfires on “gross mismanagement of the forests.”
Actor Leonardo DiCaprio responded by tweeting that the wildfires worsened due to climate change.
“The reason these wildfires have worsened is because of climate change and a historic drought. Helping victims and fire relief efforts in our state should not be a partisan issue,” he wrote.
“Mr. President it was under your watch that their budgets were cut. I’m not so left-leaning that everything done under your watch I think is bad or unjust… but what I know… what you have shown… is you are unfit to lead,” he wrote.
The blaze was part of an outbreak of wildfires on both ends of the state. Together, they were blamed for 44 deaths, including two in celebrity-studded Malibu in Southern California, where firefighters appeared to be gaining ground against a roughly 370-square-kilometre blaze that destroyed at least 370 structures, with hundreds more feared lost.
All told, more than 8,000 firefighters statewide were battling wildfires that destroyed more than 7,000 structures and scorched more than 840 square kilometres, the flames feeding on dry brush and driven by blowtorch winds.
The 42 dead in Northern California surpassed the deadliest single fire on record, a 1933 blaze in Griffith Park in Los Angeles. A series of wildfires in Northern California’s wine country last fall killed 44 people and destroyed more than 5,000 homes.
