The famously sexy foodie revealed her slimmed-down frame at a red carpet book launch in London last night, after reportedly dropping a massive two dress sizes in just months.
The Daily Mail claims that Nigella has gone from a size 16 to a size 12, and by the looks of things, she's loving her bangin' new bod.
But has the saucy 52-year-old (52? No, we can't believe it either!) ditched her love of food to achieve a showbiz figure?
Last year she famously told The Sun she had no intention of losing weight, saying: "Greed always outweighs my vanity."
"I love food and I love cooking so therefore I never deprive myself," Nigella told the UK tabloid.
And in 2006, she told Red magazine: "I'd rather throw myself out the window" than diet.
Whether she's going hungry or not, we've got to say, Nigella looks incredible in this hip-hugging Victoria Beckham number. But then again, she always looked incredible.
Do you think the celeb chef has lost weight? Or is it just a case of a miraculous pair of Spanx? Have your say below.
