Anna Wintour reveals the Met Gala 'cardinal sin' she's committed - as she confirms the three foods she's banned from the menu

Vogue's legendary editor-in-chief Anna Wintour is letting fashion fanatics in on the behind-the-scenes of the Met Gala as she revealed why this year's event broke her one 'cardinal rule.'

The 74-year-old magazine executive also confirmed the foods she had banned from the dinner menu.

Wintour divulged the secrets just days before the Met Gala in a sit-down interview with Today host Jenna Bush Hager, filmed from the Metropolitan Museum of Art's Restoration Lab.

The star-studded event is an annual fundraiser for the Metropolitan Museum of Art's Costume Institute in Manhattan, led by Wintour since 1995.

The legendary fashion figure sat down to talk more about this year's theme - including how it broke her one 'cardinal rule' - with Jenna Bush Hager

Tickets cost a whopping $75,000 each, according to CBS News. 

The gala always has a creative and whimsical theme, which celebrates the grand opening of the new spring exhibition beginning at The Met.

But Wintour admitted that this year's theme, which marks the Costume Institute's new exhibition, 'Sleeping Beauties: Reawakening Fashion,' brought some confusion. 

'This exhibition broke my cardinal rule, Jenna, which is when we came up with the title Sleeping Beauties, it's wonderful and poetic and romantic, but it actually could be many, many things,' Wintour explained.

She said that with the help of Andrew Bolton, the curator of the Met's Costume Institute, they came up with 'Garden of Time' as the official dress code.

'I fear that we've unleashed a lot of confusion out there for which I deeply apologize, but I imagine we'll see a lot of flowers,' Wintour shared.

She also broke her silence on the long-standing rumor that she had banned onions, chives, and garlic from the gala's dinner menu. 

'Well, those are three things I'm not particularly fond of, and so yes, that's true,' Wintour told Hager.

The global director of Vogue even spoke a bit about her strict no cell phone rule, which requires all guests to leave their mobile devices at home and enjoy each other's company.

Wintour also confirmed that she doesn't allow certain foods to be on the menu at the dinner, like chives and onions

Each year, Wintour hand-picks and curates the guest list, and begins the process months in advance to the May date

'It's often wonderful to hear after dinner, people say, "Oh, we had the most wonderful conversations," and so that's the idea, that life can exist without a picture on your cell phone,' she said. 

It's unclear exactly which A-list celebs will be attending this year's Met Gala, but there have been a few confirmed co-chairs of the event, which include Zendaya, Jennifer Lopez, Bad Bunny and Chris Hemsworth.

Each year, the exclusive guest list is hand-picked by Wintour, and is rarely revealed until they arrive to the event, always on the first Monday in May.

Last year, some of the guests included Rihanna and A$AP Rocky, Kim Kardashian, Kendall Jenner, Lil Nas X and Bradley Cooper.

Of course, it's all about the designers, too, with big names like Valentino, Dolce & Gabbana, and Chanel creating stunning, one-of-a-kind custom pieces for the stars. 

After guests get their photos snapped and are interviewed on the Met Steps upon arrival, they go inside for a mysterious evening that little is known about.

Wintour's no-cell phones policy means that nothing is recorded or shared with the public about the ins and outs of the event.

However, in a biography about Wintour published by author Amy Odell in 2022, a few things were revealed about the big night.

Wintour wants her guests to wear over-the-top looks, like Lil Nas X did at last year's 2023 gala

Since cameras aren't allowed in the dinner, it's unclear what really goes on in there amongst all of the A-listers - but scenes of the tables have been photographed before, like this one in 2022

Lisa Love, a longtime friend of Wintour's, explained, 'It's that English part of her. She loves a dress-up party'

Odell wrote that Wintour coordinates how the food is served on the plate based on the color pallet.

She also wrote that she loves to serve chicken pot pie at Vogue events, because it's a 'one-course meal that has everything (protein, vegetables, etc.).'

For dessert, she loved crème brûlée.

She also thinks widely about the event, including details like backless chairs for some guests who had intricate gowns that wouldn't be able to fit into a regular seat. 

The biography also revealed that Wintour encourages her guests to wear looks that are over-the-top.
