She is something of a pin-up in the cooking world, and is known for her curvaceous figure as much as her indulgent food.

But Nigella Lawson shocked fans on Tuesday by displaying a far slimmer frame than usual in her latest Instagram snap.

While the celebrity chef, 57, was excitedly filming her new BBC show in the photo, it was her noticeably smaller figure that caught the attention of eagle-eyed fans.

The culinary queen was truly radiant in the snap, which captured her in action at the hob as she cooked another delicious recipe for her new series.

Keeping casual but comfortable, the beaming brunette slipped into a slinky black dress for the stint of filming - which showed of her enviably trim figure and tiny waist to all.

However it was her famous physique that caught the most attention in the snap, leading fans to acknowledge and compliment her evident weight loss in the comments.

One shocked fan kicked off proceedings by writing: "Wow. You have lost so much weight" as others added: "Looking great!! very slim", "You are soooo slim now" and "looking so svelte Nigella!"

Further fans chimed in with more compliments to her figure, with one praising she looked: "Fit and fabulous!" while another added: "Looking beautiful as always."

Back in 2015, the London native revealed she had slimmed down from a size 16 to a size 12, but insisted that she has "never dieted", and had no intention to in the future.

Speaking to Good Housekeeping, she explained she indulges in whatever food she fancies, but simply keeps herself healthy with exercise and yoga.

She said: "I have never been on a diet to try to lose weight. I feel like I haven't lost weight, but I'm possibly in better shape.

"As you get on in life, you value feeling well as opposed to looking well. Yoga certainly makes you feel great, and you want to carry on feeling great."

However she further affirmed her beliefs that individuals should be more carefree when it comes to food, adding: "No one should be put on this earth to go on a diet! No one should eat themselves ill either."

Meanwhile the cook is heading back to the BBC with her six-part series Nigella: At My Table - which promises to inject fun into everyday meals.

Speaking of the new BBC2 series airing later this year, Nigella told the Radio Times: "I'm excited to be making this new series and to share with viewers many new recipes alongside favourites that have evolved as I've cooked them over the years."

"At My Table continues my celebration of home cooking, infusing everyday with pleasure and flavour.

"What matters most in life is the connections we have with each other and food is always at the heart of this."
