Supermodel Naomi Campbell has a net worth of the hundreds of millions, but if you think that’s impressive, you should see the net worth of her (former) boyfriend, Russian billionaire Vladislav Doronin. Doronin did what Russian billionaires do best: spend money.

He bought the Revlon spokesmodel a huge, twenty-five-room mansion for her birthday. The Horus Eye Eco-House is shaped like the Eye of Horus. In Egyptian mythology, the Eye of Horus symbolizes health, protection, and restoration. Located on Cleopatra Island in the Turkish Gulf of Gokova, the lavish mansion is energy, food, and water self-sufficient, relying on ingenious bioclimatic design to sustain itself.
