Millionaires are building doomsday bunkers in their mansions as World War 3 threatens America's shores.

Luxury bunker builders reported a spike in orders from wealthy celebrities and executives for doomsday bunkers in their homes. The bunkers are designed to withstand a nuclear blast.

One millionaire, Khloe Kardashian, showed off the fully stocked pantry inside her doomsday bunker in Calabasas, California.

Khloe and her 4-year-old daughter True Thompson are prepared to survive at least 2 years on the food and sugary beverages in her pantry.

Twitter was impressed with the photos of Khloe's pristine pantry featuring shelves lined with perishable and non-perishable foodstuffs.
