It's the first Monday in May, so you know what that means: It's time for the annual Met Gala in New York City.

The Met Gala -- formerly called the Costume Institute Gala -- serves as a fundraiser event as it kicks off the opening of the Metropolitan Museum of Art annual fashion exhibit at the Costume Institute. The 2019 theme for the event is "Camp: Notes on Fashion," and celebrities in attendance are left to interpret that as they will. The hosts for this year are Vogue's Anna Wintour (who has been a part of the Met Gala for literally as long as anyone can remember), Lady Gaga, Harry Styles, and Alessandro Michele, the creative director of Gucci.

Stars who hit the carpet include Wintour, Gaga, Styles, and Michele, along with Pose star Billy Porter (who arrived like a literal pharaoh), Riverdale's Cole Sprouse and Lili Reinhart, Laverne Cox, Serena Williams, Miley Cyrus, Liam Hemsworth, Celine Dion, Mindy Kaling, Ryan Murphy, Jared Leto, who carried a bust of his head down the red carpet, and more.

Check out the most interesting looks from the 2019 pink carpet below.
