One of the most powerful women in the world deserves a little privacy, right? She should get it on an estate this big.

Located in this remote area of France, the home known as Chateau Miraval (also a vineyard!), has been home to the Jolie-Pitt brood for nearly three years now.

At least his latest wife-to-be likes his infamous abode. The nearly 22,000-square-foot Playboy Mansion has a long history of wild parties, and is well-known for its grotto Jacuzzi.

Though he recently sold the home to a Russian billionaire, this Trump playground has everything you might need. One of the winners of his TV show oversaw the renovations.

J. Lo has nothing to cry about when it comes to the home she shares with her actor-musician hubby.

It features a tennis court, a recording studio and panoramic city views.

His home near Seattle has become a tourist attraction, where boats regularly sail by and point out his 66,000-square-foot compound on the shores of this lake.

Currently on the market for an unbelievable price, the Prince’s Hala Ranch features 15 bedrooms, 16 bathrooms and sits on 95 acres in this pricey town.

The Material Girl dropped a bundle on this four-story, 26-room mansion in one of Manhattan’s most expensive neighborhoods.

She has run into a few problems with her neighbors.

Not much is known about the actor-comedian’s $20 million estate in the gated community of Beverly Park in this famous city of stars. We do know that it was built in 2005 and uses Mission-style architecture. He currently shares the gigantic home with — well, no one since the split from his last wife. Seems like an awful lot of space for one.

Located in one of Miami’s most exclusive neighborhoods, and once the site of a famous pair hiding out from paparazzi, Diddy’s two-story home used to be owned by Mariah’s ex-husband.

His latest girlfriend joins him, too.

This late producer’s name is hardly mentioned without talking about his home, which has 123 rooms, eight two-car garages, a bowling alley and more. It’s far bigger than the vessel from his famous TV show, and was one of the hotly contested items in his will. There’s still friction in the family, though his daughter is moving on with a family of her own.

Apparently, Jerry’s house is the best summer pad around. He and his cookbook-author wife and their children call this posh Long Island community home.
