The Whitney Museum of American Art's Art Party at Highline Stages last night was called "The Groundbreakers" because it celebrated yesterday's groundbreaking for the museum's new Meatpacking District headquarters. The Whitney will relocate in 2015 from its Madison Avenue at 75th Street location to its new, $720 million Gansevoort Street home, designed by Italian architect Renzo Piano. Knicks star Amar'e Stoudemire joined Honorary Co-Chairs Shala Monroque and Eddie Borgo and Co-Chairs Sarah Brown, Maggie Betts, Tom Dunn and Whitney Director Adam D. Weinberg. "I grew up in the art world and really appreciate art, so I wanted to keep a foot in the world of contemporary art," said Brown of the museum's appeal.
