The 27-year-old stunner, who married her partner Ricky Van Veen in September, is the guest editor for the magazine's November issue and talked about her love of spanks, her questionable cooking skills and her style icons.

Williams showed off her impressive abs and toned figure as she posed in a pair of black leather trousers and nothing else.

Williams posted the image to Instagram, alongside the caption: "I am particularly proud of this one. For my whole life until 2 years ago, I was super self-conscious about my stomach. I dreaded bikini season," she said.

"I kept it covered. Boyfriends weren't allowed to touch it. No amount of crunches seemed to strengthen it. Then I met @ilariacavagna who introduced me to the magic and focus of Pilates."

"I have never felt stronger, healthier, more focused, or more feminine. Now, I love my stomach because it keeps me grounded to my core. And it's still the same stomach! Here's to proving yourself wrong."

Talking about how she achieves her flat stomach, Wililams told Harper'z Bazaar that she credits Spanx for her svelte figure.

"This is my gift to you: Spanx makes the most incredible exercise spandex." she said.

"I wear them almost every day. They have a little control top, so they’re flattering. I’ll often stay in exercise clothes all day, which I know is a faux pas."

The star said she loves timeless fashion pieces, which leads nicely into her favourite style icons.

"When it comes to my style icons, I’ve always had a thing for the K’s: [Diane] Keaton. [Grace] Kelly. [Diane] Kruger. Kate [Moss]. Katharine [Hepburn]," she said.

"They all represent sophisticated fashion that’s also full of life."

'After all, clothes are fun – it’s dress-up for adults. I’d like to call my style easy, timeless, and rustic preppy (if that’s a thing), which most often translates as endless button-downs, a chic pair of boots, a good variety of sweaters, and my staple – jeans.'

Speaking to the issue about her cooking skills, the Hollywood star said she eats out a lot.

"I am the world’s worst cook," she said.

"When I cook, the salad is done first and is soggy by the time you eat, the pasta is al dente, but not in a good way. And I’m perpetually worried that the meat is going to poison everyone, so it ends up being black. It’s a nightmare, so I just order in."
