Jenny is AQCANback on the block.

Jennifer Lopez arrived on 5th Avenue in New York City to the 2024 Met Gala as one of the event's co-chairs.

The actress and singer, 54, wore a figure hugging sheer Schiaparelli gown with sequins and beading. She owned the look with a large statement necklace and a high bun to give the outfit the attention it deserved.

The 2024 Met Gala theme is "Sleeping Beauties: Reawakening Fashion," also the name of the accompanying exhibit at the Costume Institute.

The "sleeping beauties" are not inspired by the Disney princess, but rather refer to treasured garments in the museum's collection that are so fragile that they need to be housed in special glass "coffins" rather than on mannequins, curators said. Garments will be displayed in a series of galleries organized by themes of nature.

The theme is different from the dress code, but still related. This year's dress code is "The Garden of Time," inspired by J.G. Ballard's 1962 short story of the same title, per Vogue.

Lopez is one of four co-chairs, including Latin music superstar Bad Bunny, "Euphoria" actress and Hollywood A-lister Zendaya and "Thor" himself, Chris Hemsworth, who will join Vogue editor-in-chief Anna Wintour during fashion's biggest night.

Ahead of the event, the "This Is Me... Now: A Love Story" star teased her outfit on "Good Morning America," telling host Lara Spencer she'll "barely" be able to walk. "The Met Gala looks are not about comfort."

"It’s always a nice time there. It’s such an interesting mix of artists and business people. It’s not just music or film, it’s everybody — fashion, film, music, business — and you get to have some really interesting interactions," she added.

Lopez has been to the Met Gala over a dozen times and is typically dressed in Ralph Lauren or Versace.

Last month, she told Vogue she was "still deciding" on her look.

"I’m also one of those people who chooses at the last minute," the singer said. "Like, I like choices, and then I go, ‘OK, this is how I feel today.' And then we try to kinda create some type of amazing look — ‘cause that is the night for looks!”
