Popular designer, Vera Wang has revealed some surprising secrets that help her maintain her youthful appearance.

The 74-year-old fashionista, who has long wowed fans with her toned physique and ageless body, said she is a big fan of fast food.

'I do eat McDonald's, absolutely, I order it every day, like two weeks on it, and then I’ll change,' Wang - who recently admitted that she is 'frightened' of getting older - told Page Six at the DKMS Gala in NYC on Thursday.

The wedding dress designer also admitted she enjoys Dunkin' Donuts, sharing: 'I like the cream-filled, sugar-coated donut. It’s like a jelly donut, but it’s cream inside, vanilla cream. I like the pink with sprinkles, too.'

The star previously shared in 2020 that her anti-aging secrets included 'work, sleep, a vodka cocktail [and] not much sun.'

The beauty also told Page Six that her work life keeps her young.

'Basically, I've worked my whole life, so it's really been about work. I think work keeps you young and stimulated.'

'I work very long hours, I’ve raised two daughters. I think keeping busy is the best antidote [for] good health.'

Wang, who wowed fans last year when she showed off her incredible physique in a series of pictures from her 73rd birthday bash, admitted her bigger concern is avoiding a physical disability.

She told Daily Mail: 'I think what happens sometimes as you age... I'm more frightened about physical disabilities... not all this.

'I'm not totally preoccupied with how I look. I love my work, and I'm very passionate about my work, my friends, my daughters... I mean, I have a very full life.'
