With her famous curves and glossy dark hair, Nigella Lawson could easily be cast as an Italian screen siren.

And today, the TV cook, 52, looked like she was straight out of a Sixties Italian movie as she posed on a vintage-style Lambretta scooter.

Showing off her slimmer, but still curvy figure in a black dress, the mother-of-two was shooting an advert for an upcoming feature in the Mail On Sunday.

Nigella is returning to bookshelves and TV in the next few months with her take on Italian food.

As well as the release of Nigellissima: Instant Italian Inspiration on hardback on September 13, she will follow with a new TV show on September 24.

Earlier this week, she showed off her hourglass in a fitted, all-black outfit, consisting off a long-sleeved top, tight black jeans and knee-high boots.

Nigella's debut of her new size 12
shape – down from a size 16 – came after she admitted back in April that she had been struggling
to eat because of a painful foot operation.

She said at the time: 'I have indeed lost weight.
Almost a year ago, I had a very glamorous operation – a double
bunionisation.'

'I couldn’t walk to the fridge afterwards. Actually, it’s quite a good diet; not because I stopped eating, but
because you can say to someone, “Can you get me a slice of cake” but
it’s kind of embarrassing to say, “And now could you get me a second
slice”'

However, despite Nigella's
revelations about the operation, it was later reported that she had been
following the Bodyism Clean and Lean plan – a healthy eating programme
devised by James Duigan, personal trainer and nutritional advisor to
models Elle Macpherson and Rosie Huntington-Whiteley and actor Hugh
Grant.

An integral part of the plan is
taking a selection of Duigan's powerful Bodyism health supplements,
taking a cocktail of vitamins, minerals and fish oils that help to burn
fat and fight cravings.

Meals on the Clean and Lean diet plan
include plenty of fresh fish, lean meat including skinless turkey and
chicken, and fresh, preferably organic vegetables.
