Vogue‘s Editor in Chief, Anna Wintour, spearheads the guest list, and if you’re not invited, you’re definitely not going. Confirmed guests include Blake Lively, Ryan Reynolds, Chadwick Boseman, Lupita Nyong’o, Bradley Cooper, Katy Perry, Jared Leto, Priyanka Chopra, Nick Jonas, and Lena Waithe. Lady Gaga, Harry Styles, Serena Williams, and Gucci Creative Director Alessandro Michael are this year’s co-chairs.
