The Met Gala is the event of the season.
Vogue cover girls like Beyoncé and Rihanna have become red carpet regulars at the party, which Anna Wintour has overseen since 1995. It's become one of the biggest fundraisers in New York City—just last spring, the Anna Wintour Costume Center raised about $13.5 million. This year's co-chairs include Tom Brady, Gisele Bündchen, Katy Perry and Pharrell Williams.
Scoring an invite is a sign you've made it, and guest lists are submitted to Wintour for approval. Céline Dion will make her debut at the 2017 Met Gala, wearing a custom Versace design. Fans can expect to see a mix of actresses, athletes, chefs, models and singers walking the red carpet.
The event was started in 1946. But, unlike Blake Lively and Taylor Swift, not every Vogue cover girl has climbed the museum's steps. Here, E! News looks at A-listers who've yet to attend:
