N6. Madonna
Her art collection is almost as big and legendary as herself. The entire collection is estimated at $100 million, and includes some of the big-time names.
Among the private collection she has at her place, Picasso, Hopper, Kahlo, Leger, Dali, Man Ray and Hirst are displayed all over the house.
Madonna is also a huge fan of Tamara de Lempicka, a Polish Art Deco painter known for her glamorous lifestyle, whose work Madonna perhaps fittingly helped bring back into the limelight.
Unlike many other celebrity collectors, Madonna employed an art adviser, Darlene Lutz, until they became embroiled in a lawsuit over a painting in 2005.
