Jared Leto, now a pro at this, had yet another wild costume at the 2023 Met Gala in New York City on Monday (May 1). He dressed up like a cat.

A big, fluffy white cat.

But not just any cat! As those familiar with the affluent fete each year are likely aware, every Met Gala has a different theme. At this year's Metropolitan Museum of Art soiree, the gala honored late German fashion designer Karl Lagerfeld. Leto, the actor who also sings in the band Thirty Seconds to Mars, was dressed as Lagerfeld's beloved pet cat Choupette.

The reactions to the cat costume at the Met Gala were priceless. As were those on Twitter that dug into the photos and the interactions between Leto and other Met Gala guests.

As pointed out by People, fellow Hollywood actors such as Anne Hathaway and Salma Hayek marveled at Leto's cat costume, especially once he removed the giant cat head to reveal that it was him. Photos from the moment also show other stars' responses.

"Seeing a giant cat vs realizing the cat is Jared Leto," one sly Twitter user remarked on two images that show the hip-hop artist and singer Lizzo's reaction to Leto.

Leto didn't stay in his cat costume the whole time, as the photos show. He eventually revealed an all-black dress-and-cape getup with bling on the shoulders and neck.

And that's not all. Others on the red carpet had some zingers for the Thirty Seconds to Mars singer.

For example, the actress Aubrey Plaza told Variety she wished Leto had kept the cat costume on with his head still covered. She said it's what Lagerfeld would have wanted!

Thirty Seconds to Mars are working on new music — over the last several days, they said they leaked a new song. But they haven't yet shared where it is.

See more reactions below — especially since the singer Doja Cat also dressed cat-like — followed by pics of Leto's 2019 Met Gala head costume.
