Spencer Pratt and Heidi Montag are suing the city of Los Angeles and the Department of Water and Power, alleging that the agencies' management of the water supply directly caused damage to their home in the Pacific Palisades Fire.

The lawsuit faults the Los Angeles Department of Water and Power for delaying repairs to a massive reservoir that services the Pacific Palisades.

The Hills stars Spencer Pratt and Heidi Montag previously showcased their home in a tour, years before losing it amid the ongoing Los Angeles wildfires. Fueled by dry conditions and strong winds, the fires have caused unprecedented devastation across Southern California over the past several days, with damages estimated at up to $150 billion.
