She may be an “Uptown Girl,” but Christie Brinkley prefers to spend her time in the Hamptons.

Christie Brinkley isn’t your everyday supermodel. The blond beauty is a business tycoon in her own right, thanks to her thriving skin-care line and various business ventures. And who could forget those fitness infomercials with Chuck Norris? Now she’s listed yet another Hamptons, NY, estate, this time in the peaceful seaside community of Sag Harbor, NY. The five-bed, five-and-a-half-bath Colonial is just like Christie: a chic American classic that never goes out of style.

Now that her kids are all grown up, we’re guessing, the supermodel is ready to downsize. And since her real estate portfolio rivals Warren Buffett’s, she’s ready to say goodbye to this stylish, 5,500-square-foot spread — for $25 million. The three-story property, which was built in 1843, is located on a stunning 4½-acre lot with 327 feet of sandy beachfront. With breathtaking views of the harbor and sailboats of North Haven, NY, the home has many original period details, including grand columns, wide-plank pine floors, and multiple fireplaces. A beautiful kitchen with soapstone and marble counters complements a formal dining room and spacious living room. An impressive master suite has its own sitting room and terrace, which is ideal for taking in panoramic views of the harbor. Lush gardens, specimen trees, and a gunite pool surround the house, which is just a short walk from thriving Main Street.

Christie, who split from her boyfriend, rocker John Mellencamp, in August (he previously dated Meg Ryan), is quite the real estate aficionado. Back in June, she listed her massive Bridgehampton, NY, estate for $29.5 million. In fact, Christie’s real estate empire may beat out ex-husband Billy Joel’s: He has also recently downsized, ditching his Florida compound just a few years after listing his Sagaponack, NY, estate and his Miami, FL, mansion.
