Victoria Beckham squeezes into her tightest trousers ever

But for the wrinkles at the knee and ankle, you would swear they had been painted on.

Victoria Beckham stepped out yesterday in one of the tightest pairs of trousers ever seen on the streets of London.

Woman in black: Victoria revealed her extremely skinny legs in a pair of PVC leggings in London's Mayfair today

She has jetted in to London from Los Angeles to support husband David as he wins his 100th England cap in the friendly match against France.

Dressed all in black, with her customary outsize sunglasses and Christian Louboutin shoes, the 33-year-old indulged in a little retail therapy at designer store Balenciaga before popping into trendy Mayfair fish restaurant Scott's for a bite to eat.

Her leather leggings, however, can surely not have left room for much food. And judging by her slender thighs, any weight she gained during the Spice Girls' recent world tour has been rapidly shed.

The Spice girl burns more calories as she indulges in some retail therapy

It was reported that Posh, who hates taking exercise, was forced to raise her calorie intake to perform the choreographed dance routines on stage.

Before that her favoured food was said to be steamed fish and edamame beans.

Her latest weight-loss diet, however, is claimed to consist of prawns and strawberries.

Posh could be feeling the pressure to remain a size zero after launching her new range of denim, dVb Style, in the U.S. last month.

Her LA chums Eva Longoria and Kate Beckinsale are similarly proportioned.
