Posh tries out her new 'Ninja Turtle' look in Malibu

As a high-profile fan of Versace, Cavalli, and Dolce and Gabbana, Victoria Beckham has shown her taste for Italian style.

Now it seems she is extending her patronage to Leonardo, Michelangelo, Donatello and Raphael.

The Spice Girl stepped out in Los Angeles at the weekend in a satin frock which might have taken its inspiration from the Teenage Mutant Ninja Turtles.

The lurid green was a similar shade to the skin of the cartoon heroes - named after the four Italian masters and famous for the phrase "cowabunga, dudes" - while its segmented design offered a nod to their armoured shells.

One onlooker said: "Victoria's dress was obviously couture and massively expensive. It was exceedingly well cut and fitted her like a glove.

"But the green satin tiles gave it a turtle-like, body armour feel. Sadly, the only things marking her apart from being the fifth member of the Ninja Turtles were the lack of a coloured eye mask or a samurai sword."

Mrs Beckham, 33, also shunned another Ninja Turtle tradition - pizza. She and her husband David, 32, instead dined on sushi at the Ivy restaurant in Malibu.

Since moving to LA two months ago, the singer has made quite an impact with her fashion sense. Though her eponymous jeans range sold out in department stores, she has been mocked for her overly made-up look and formal taste in clothes.

Perhaps the latest outfit was an attempt to come out of her shell.
