Gloria Gaynor belted out “I Will Survive” at a 20th Anniversary Gala for the Andy Warhol Museum in Pittsburgh on Saturday night.

Spotted in the crowd were New York art dealer and Heidi Klum’s beau Vito Schnabel, Warhol biographer Bob Colacello, Warhol “superstar” Baby Jane Holzer, Vincent and Shelly Fremont, designer Misha Nonoo and Veronica Bulgari.

The evening started with a VIP preview of the exhibition, “Halston and Warhol: Silver and Suede,” followed by a black-tie dinner and dance party.

Paddle8’s Alexander Gilkes led an auction that raised more than $500,000 for the museum.

At midnight, the museum opened to the public as DJ duo AndrewAndrew spun tunes till 2 a.m.
