The Met Gala looked a little different two years ago, but it’s back on this year with attendees sure to pull out all the stops. Throughout the years, the star-studded event has been the site of some unforgettable celebrity moments—from Lady Gaga’s elaborate striptease to Rihanna’s riveting performance on top of a dinner table. And who could forget when Taylor Swift and Tom Hiddleston were first caught dancing flirtatiously with each other, kindling the Hiddleswift phenomenon? Take a walk down memory lane with this list of the craziest celebrity moments.
Lady Gaga bares it all, 2019

There are, quite simply, no words for the performance Lady Gaga put on at the 2019 Met Gala. The actress and singer showed up in a fuschia Brandon Maxwell cape gown with a 25-foot train, taking off layer after layer until she was writhing on the steps of the Met in lingerie, fishnets, and sky-high heels. Nobody does it better!
Billy Porter gets carried in on a litter, 2019
Billy Porter set a new standard: How else would one enter the Met Gala if not carried in by six shirtless men? Things only got more jaw-dropping from there, as the Pose star showed off a custom “Sun God” ensemble by The Blonds, which included a bejeweled catsuit outfitted with 10-foot wings, a 24-karat gold headpiece, as well as custom gold-leaf Giuseppe Zanotti shoes and fine jewels by Andreoli, John Hardy, and Oscar Heyman.

Jared Leto accessorizes with his own head, 2019

Why stick to jewelry or watches when you can walk down the Met Gala carpet holding your own head as the ultimate accessory? That’s exactly what Leto did in 2019, courtesy of Gucci (the severed heads first appeared on the fall 2018 runway), and it was both terrifying and impossible to look away from.
2 Chainz “proposes” to Kesha Ward, 2018
It was the moment nobody expected: rapper 2 Chainz proposed to partner Kesha Ward on the Met Gala red carpet. Getting down on one knee, he popped the question and Ward (thankfully) said yes, as the crowd of photographers snapped and cheered away. But not so fast: it appeared the couple was already married, so consider it more of a reaffirmation of their affection. Or an excuse for Ward to wear a new ring.
Katy Perry’s outfit needing an open-top vehicle, 2018

For 2018’s “Heavenly Bodies” theme, Katy Perry descended upon the Met wearing a custom Versace creation complete with angel wings. It was one of the night’s more meme-worthy ensembles—and the best part was that it needed an open-top vehicle to get here to the venue. Before the red carpet, the singer was spotted taking a casual drive on the Manhattan streets, her theatrical wings out for all normal pedestrians to see. She created a moment before the event even started.
Jaden Smith carries his own dreadlocks down the red carpet, 2017
Several weeks before attending the gala, Smith chopped off his bleached dreadlocks for an upcoming role in Life in a Year. The dreads found a second life, however, on the red carpet of the Met Gala—a one of a kind accessory, if you will. Smith’s hair caused quite a stir, but the 19-year-old actor kept his explanation vague: “I couldn’t bring my sister as a date, so I brought my hair.” Perhaps an homage to her earworm hit, “Whip My Hair”?

Rihanna dances on a table in 2015

Sarah Jessica Parker breaks the Internet in 2015

Beyoncé hits the red carpet solo after Lemonade in 2016
After Beyoncé premiered her groundbreaking album Lemonade, the singer was subject to an endless amount of speculation, particularly regarding the state of her marriage to Jay Z. A week after the premiere, Queen Bey surprised everyone by appearing solo on the red carpet wearing a nude latex Givenchy number (cue the Internet jokes about whatever happened to “Becky with the good hair”).

Amal Clooney and George Clooney make their relationship Met Gala official in 2015
It was their first time stepping out at the Met Gala as Mr. and Mrs. Clooney, and they certainly did not disappoint.
