The A-listers who weren't at the blowout Saint Laurent show in Los Angeles last night, piled into Cipriani Wall Street to kick off Fashion Week with the 2016 amFAR Gala. The evening honored Harvey Weinstein, a longtime supporter of amFAR and HIV/AIDS research. Leonardo DiCaprio was, of course, glad to be in his usual cloud of leggy blonde models (i.e. Heidi Klum, Hannah Davis, Petra Nemcova), while Jay Z shared plenty of laughs with his Tribeca neighbor, Robert De Niro. Though Mr. Carter was without his wife, Beyonce, lovey-dovey couple Blake Lively and Ryan Reynolds provided plenty of PDA for the occasion.

While the event put philanthropy at the forefront, it was not without its fair share of fun. Charli XCX took to the stage alongside Icona Pop for an energetic performance amid proceedings led by screen sirens Diane Kruger and Uma Thurman.

Who was there: Guests included Jay Z, Leonardo DiCaprio, Robert De Niro, Diane Kruger, Hailey Baldwin, Blake Lively, Ryan Reynolds, Kelly Gale, Kenneth Cole, Adriana Lima, Carol Alt, Emily Ratajkowski, Giovanna Battaglia, Harvey Weinstein, Heidi Klum, Icona Pop, Karolina Kurkova, Lizzie Tisch, Padma Lakshmi, Paris Hilton, Nicky Hilton, Uma Thurman, Charli XCX, Rachel Zoe, Chanel Iman, and Jourdan Dunn.
