Nigella Lawson labelled a fake after showing off even slimmer figure at book signing

Nigella Lawson is best known for two things: delicious food and her curvaceous figure.

But after already losing a lot of weight, the British celebrity chef has set tongues wagging again as she showed off a far slimmer frame than usual at signing for her new book, At My Table.

Shocked fans were quick to comment on her figure, with many questioning her on the new look.

One said: "Hardly recognise her, looks 5 years younger and very slim!"

While another added: “Don't believe she lost that weight by eating emergency brownies #thinkwearestupid."

A third said: "She looks gorgeous, but it's hard to believe she is as indulgent and hedonistic as she was before that degree of weight loss."

"Please put some weight on. You look good but before you looked amazing,' a Twitter user commented.

Another said: "Sweetheart, put some weight on, you’re too thin."

The domestic goddess has slimmed down from a size 16 to a size 12 and has put the impressive body change down to her love of yoga - and eating small portions.

The 57-year-old previously 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.

"No one should be put on this earth to go on a diet! No one should eat themselves ill either," she added.
