Spencer Pratt will leave Los Angeles if he isn't elected the city's new mayor.

The 42-year-old reality TV star has vowed to pursue "the last American dream" in another US state if he isn't successful in his bid to become the city's next mayor.

He told comedian Adam Carolla: "If Karen Bass gets re-elected, or Nithya [Raman] gets elected, I will be done with trying to live in Los Angeles."

In 2025, Spencer and Heidi Montag, his wife, filed a lawsuit against the city of Los Angeles and the Department of Water and Power (LADWP) after their home was destroyed in the Pacific Palisades fire.

Spencer is determined to win his legal case, but admits that he might look to rebuild his life in another state.

He explained: "I'll take that money from the [Gov. Gavin] Newsom state park and the LADWP, and I'll go find somewhere that my kids will not have to see naked zombies and I can have the last American dream somewhere.

"I will not rebuild if these people are in charge. Because what would I be putting money into?"

Spencer launched his campaign to become the mayor of Los Angeles earlier this year.

The reality TV star - who has been married to Heidi since 2008 - observed that the system in Los Angeles is "fundamentally broken" and then promised to overhaul the situation if he's elected the next mayor.

Spencer said: "The system in Los Angeles isn't struggling, it's fundamentally broken. It is a machine designed to protect the people at the top and the friends they exchange favours with while the rest of us drown in toxic smoke and ash.

"Business as usual is a death sentence for Los Angeles, and I'm done waiting for someone to take real action. That's why I am running for mayor."

Spencer promised to overhaul the city while speaking at the They Let Us Burn! protest.

The Hills star explained: "This is a mission, and we're gonna expose the system.

"We're going into every dark corner of Los Angeles politics and disinfecting the city with our life and when we are done, L.A. is going to be camera-ready again."
