Vera Wang just revealed that her youthful glow doesn’t have anything to do with maintaining a clean diet.

The famed fashion designer, 74, talked about her fast-food habits and her aging philosophy with Page Six at Thursday’s DKMS gala in New York, an annual event run by the Deutsche Knochenmarkspenderdatei nonprofit.

Revealing how she’s not one to keep to a restricted meal plan, Wang admitted to sometimes eating fast food for days on end.

“I do eat McDonald’s, absolutely,” said the bridalwear visionary, who has previously been photographed with a burger and french fries from the chain. “I order it every day, like two weeks on it, and then I’ll change.”

She’s not averse to sweet things either, telling Page Six about some of her go-to Dunkin’ orders.

“I like the cream-filled, sugar-coated donut,” she said. “I like the pink with sprinkles, too.”

While eating lean doesn’t seem to factor into Wang’s wellness plan, she actually credits her high-stakes fashion career with maintaining her ageless appearance.

“Work keeps you young and stimulated,” she told Page Six, adding that her hectic schedule has also included raising two daughters. “Keeping busy is the best antidote [for] good health.”

The designer has dressed some of the most famous brides of all time, working on wedding looks for celebs like Victoria Beckham, Gwen Stefani, Hailey Bieber and Ariana Grande.

Wang previously attributed her clock-stopping looks to not only her job, but the occasional cocktail.

Back in 2020, she told an Instagram follower that her self-care routine included “work, sleep, a vodka cocktail, [and] not much sun.”

The fashion legend is also the proprietor of the adult beverage brand Vera Wang Party, which sells both a classic prosecco and bubbly rosé.
