Invites for the May 6 Costume Institute Benefit are starting to arrive, and they feature a surprise high-wattage celebrity name — Beyoncé.

Beyoncé Knowles has been added to this year’s gala as honorary chair. While unconfirmed, it’s possible the entertainer could join co-chairs Rooney Mara, Givenchy’s Riccardo Tisci, Lauren Santo Domingo and Vogue editor in chief and Condé Nast artistic director Anna Wintour on the receiving line.

The benefit celebrates the “Punk: Chaos to Couture” exhibition, which runs at the Metropolitain Museum of Art from May 9 to August 14.
