The 32-year-old pop star lost her Malibu mansion in the 2018 wildfires and now that a similar blaze is raging across Pacific Palisades in Los Angeles, she has recalled the moment she was met by a "pile of ash and rubble" where her front door used to be.
"This image hits me hard in the heart today," she wrote on Instagram alongside a photo of the remains of her old home.
"This is a photo taken of my front porch in 2018 after losing our house in the Woolsey fires.
"It's a feeling you don't ever forget. Walking up to the door you would pass through daily, looking forward to being greeted by the ones you love like you always do but instead being met by a pile of ash and rubble."
The Grammy Award-winning star - who was married to Australian actor Liam Hemsworth at the time and alluded to the tragedy in her 2023 break-up anthem Flowers - is "beyond heartbroken" at the current situation, especially because it is all happening in a city that represents "living the dream" to so many.
"My soul aches for those who are experiencing this devastation firsthand and I cry for my city," she said.
"It's beyond heartbreaking. Los Angeles represents 'living 'the dream' but the reality today is wreckage and destruction."
She concluded her post by calling for others to help where they could and sent her love to those affected.
"I am sharing links to organizations that I'm personally supporting and that are helping fight the fires and support survivors, including @malibufoundation that we helped launch in 2018," she said.
"Time , resources and dedication from inside and outside of our community will heal us, but it hurts deeply for now."
Thousands of homes have been destroyed including those belonging to former The Hills stars Heidi Montag and Spencer Pratt, acting partners Leighton Meester and Adam Brody and a mansion belonging to Scary Movie actress Anna Faris.
Paris Hilton - who is married to Carter Reum and has Phoenix, 23 months, and 14-month-old London with him - is also among the celebs to have lost a home.
John Goodman - who is known for his roles in The Flintstones and Roseanne - has also seen his home destroyed in the wildfires as his Pacific Palisades property was in the path of the main blaze.
Sir Anthony Hopkins' home is also gone, according to pictures, while Top Gun: Maverick star Miles Teller and his wife Keleigh Sperry's $US7.5 million ($A12.2 million) mansion was also wiped out.
Nothing remains of Billy Crystal's sprawling home beyond his tennis courts - which were virtually unmarked despite his house lying in ruins beside the green grounds.
