A woman smitten at the sight of Mikhail Baryshnikov fainted at the Stephen Petronio opening- night benefit gala at the Joyce on Tuesday night. When the ballet legend made his way through the crowd, greeting guests as he joined the audience, a witness told us one unnamed attendee could hardly contain her excitement and passed out on the spot. The woman came to shortly after and enjoyed the show and after-party at the Hotel Americano, while Baryshnikov made it into the theater unfazed. Other guests at the gala included designers Karen Erickson and Tara Subkoff, Terence Koh, Lauren Remington Platt and Cecily Brown.
