On vast private estates further East, the good works continue! The Beach Ball, to benefit the Bellport Boys and Girls Club, draws a financially above-average (or at least over-leveraged) crowd including aging Lancome model Isabella Rossellini and daughter, Elettra Rossellini Wiedermann—who inherited her mother’s looks and Lancome contract—talk show pooh-bah Charlie Rose, designer (and Eva Mendes appendage) Francisco Costa, British artist Hugo (Pint of) Guinness, and former Massachusetts governor William Weld. Later, it’s the Beaches and Bays Gala at the swell East Hampton home of Robert Lion Gardiner—heir to Gardiner’s Island, that five-mile patch of pricey real estate off the shore—benefiting the Nature Conservancy’s quest to save our natural resources from waterfront estates. Finally, the American Cancer Society hosts “Denim & Diamonds” in Southampton, honoring the Count and Countess deLesseps—now appearing on Real Housewives of NYC; the other tarts … er … stars of which will also be stopping by—and the late great actor Roy Scheider, and featuring an honorary committee including Chevy Chase and Jayni Chase, Itzhak Perlman and the missus, and thespian Kelsey Grammar with his bride, Camille. The dress is “Denim Chic.” Hey, somebody see if Kathryn Tucker can spare a slutty bridesmaid or two.
