Keira Knightley – $6 Million, New York

Keira Knightly started pouring millions into her bank account since she began acting at a very young age. However, unlike most child celebrities who would spend their hard-earned cash in lavish lifestyles, Knightley planned ahead and made sure to invest in a prime real-estate property. Her prized possession is her apartment in Manhattan’s TriBeCa neighborhood. The 2-floored apartment has three bathrooms and three bedrooms spread across the 3,820 square feet area. It also has a private patio that has an area of 900 square feet.
