School's Out, the annual summer benefit for the Hetrick-Martin Institute, home of the Harvey Milk School for gay, bisexual, transgender and questioning youth, has become the it event for every social gay on the East Coast. Last weekend, the fundraiser was held at Grey Gardens, the former house of Big and Little Edie Bouvier Beale (and the subject of Albert and David Maysles' 1975 documentary and the 2009 TV movie starring Jessica Lange and Drew Barrymore) -- aka every gay's ultimate dream locale. The guest list was a who's who of power gays, like Bravo's Andy Cohen, designer Dennis Basso, shoe god Brian Atwood and Dr. Jake Deutsch, Scott Currie, Kristian Laliberte, Timo Weiland, Christian Leone, Matthew Marden, Marcus Teo, Thomas Krever and event chairs O'Brien Kelley, Peter Wilson and Brendan Monaghan as well as hosts Boykin Curry and wife Celerie Kemble (a straight couple!) and Bronson van Wyck and Andrew Fry. "It was a super chic crowd," Monaghan told me. "And the most money we ever raised for that event and the only event that has sold out so fast -- in three weeks." The night raised a whopping $180,000. Afterwards, the boys (and a few straight girls) headed to The Almond for the after-party. FYI: The Almond on weekends is the nexus of the gay Hamptons scene, so book your booth now.
