Spencer Pratt and Heidi Montag's home destroyed in devastating LA wildfires

Raging wildfires across California have sadly destroyed the family home of The Hills stars Spencer Pratt and Heidi Montag, reports say.

Spencer's sister Stephanie Pratt has since taken to social media to express her heartache following her family's loss.

A 1,200 acre bushfire broke out on Tuesday of this week (7 Jan), and has since continued to spread across several prolific Los Angeles neighbourhoods.

According to the Mirror US, the homes of countless huge-name stars are currently under threat, including the likes of Tom Hanks and wife Rita Wilson, Reese Witherspoon and her family, Miles Teller and wife Keleigh, and Adam Sandler, his wife and their two children.

The families of Steve Guttenberg and Michael Keaton - all of whom live in the area - are also at risk.

Governor of California Gavin Newsom declared a state of emergency for Ventura and Los Angeles counties on Tuesday afternoon, revealing that over 30,000 had been ordered to evacuate and that 'many structures' in these areas were 'already destroyed'.

As we say, amongst the thousands of Los Angeles residents who've sadly seen their beloved home go up in flames are reality TV couple Spencer Pratt and Heidi Montag.

According to local news outlets, the wildfire ripped through the Pacific Palisades neighbourhood, engulfing their property - in which the on-screen couple raised their two sons, Gunner and Ryker - in fire and smoke.

Thankfully, however, the married pair - who shot to fame in the early noughties after being cast for reality docu-series The Hills before wedding i 2008 - managed to escape the property earlier on Tuesday along with their children.

Prior to their evacuation, 41-year-old Spencer took to social media to show footage of Los Angeles Fire Department officials attempting to control the fire encroaching onto their home from across the mountains.

On his Instagram Story, firefighters could be seen attempting to douse the fire with water being dropped from above by emergency airplanes.

Sadly, however, their attempt was to no avail, and their property was amongst those in the Palisades area that was burned to the ground.

Spencer's sister and former Made In Chelsea star Stephanie Pratt also took to social media to confirm the fate of her brother's home.

Revealing she'd been in London when the fires broke out, she shared a photo of Spencer where the fires could be seen in the background.

"I am beyond heartbroken for my brother, Heidi & the kids," she wrote. "And to all of our friends and neighbours who have lost their houses today.

"Just spoke to my dad - he tried to save my brother's house but the wind is so strong there was nothing he could do. Even the fire station in the palisades has burned down. The Pacific Palisades is completely on fire. No one is there."

Stephanie, 38, went on to explain: "My parents evacuated safely and are watching the fire rage towards their house on security cameras. I don't even want to look at mine as my dad told me the Market down the street from my house is on fire."

The cause of this week's wildfire currently remains unknown.

Red flag warnings across the majority of Southern California remain in place until Thursday afternoon.
