Madonna and Jennifer Lopez were among a who's who of Hollywood's elite who hit the red carpet in New York City for the annual Metropolitan Museum of Art's Costume Institute Gala Benefit.
This year's event, Alexander McQueen: Savage Beauty, honoured the work of the late designer, who committed suicide in February 2010 at the age of 40.
"I miss him terribly, not only as a person but as a designer," said a visibly emotional Madonna, who was wearing a gown by Stella McCartney.
"I think the fashion business is a little bit dull without him and I loved his provocative punk rock attitude. I think his designs were brilliant. I think he was brilliant. And I hope he's having fun wherever he is right now."
Others who walked the red carpet included J-Lo and husband Marc Anthony, Gwyneth Paltrow, Penelope Cruz, Jessica Alba, Fergie and Sarah Jessica Parker.
And what must have surely been one of the hottest line-ups of the year also included Blake Lively, Kristen Stewart, Rihanna and Beyonce
Many of the stars opted for gold and silver gowns with Nicole Ritchie, Jessica Alba, Kate Hudson, Ashley Greene, Emma Roberts, Naomi Watts and Elizabeth Banks all resplendent in neutral tones.
Gisele, Lea Michele, Dianna Agron and J-Lo turned heads in red, with K-Stew's diamond pattern red Proenza Schouler dress dividing the style critics. Michelle Williams and Penelope Cruz wore understated black, while Eva Mendes shone in a royal blue fluid Stella McCartney gown.
But it was Blake Lively who ensured she was queen fashionista of the night by wearing Chanel and arriving on the arm of Karl Lagerfeld.
The Savage Beauty exhibition will be on display at the Metropolitan Museum of Art from May 4 to July 31.
