The Silk Building penthouse that Britney Spears once occupied is back on the market. Thanks to a new paint job and some kitchen renovations, it's now on the market for $6.595 million (or more than $2 million more that Spears sold it for). The best feature of the apartment? The long list of famous people who have lived there. In addition to a pre-Federline Brit, the pad has also been home to Russell Simmons and Keith Richards, which means there's about a 50 percent chance you'll go crazy or abuse drugs if you move in. More photos after the jump.

Is Tom Cruise moving to New York? The answer is yes—at least temporarily. Cruise and the kids are following Katie Holmes to Manhattan when she makes her theater debut in "All My Sons," which opens in October. That means for 16 weeks (at least) the crazy Cruises will be bunking down here in the city, although their precise whereabouts still haven't been determined. While the fam's been staying at The Carlyle as of late, Katie's rumored to be checking out furnished Upper East Side rentals in the $60,000 per month and up category. Whether they'll buy or rent might still be up in the air, but settling down on the UES makes perfect sense: The "Scientology Celebrity Centre" is on East 82nd Street between Fifth and Madison.

Philip Seymour Hoffman and longtime girlfriend Mimi O'Donnell have gone into contract on a fifth floor loft at 68 Jane Street. The three-bedroom, pre-war apartment—which was listed for $4.4 million—features high ceilings, a wood burning fireplace, and authentic doors from Provence. Photos after the jump.

So long, Soledad O'Brien. The CNN correspondent, her banker hubby Charles "Brad" Raymond, and their ridiculously adorable brood of four kids are leaving their West 24th Street co-op. They're asking $4.6 million for the 4,000 square foot space, which features a 42-foot-long living room and which underwent exhaustive renovation to make it more kid-friendly. Photos follow after the jump...

After the jump, pics of the $5.4 million Amagansett home where Gwyneth Paltrow spends her summers relaxing with Apple and Moses, and consoling hubby Chris Martin over his flailing musical career.
