Posh's knobbly knees are the talk of New York

Her famously slender legs were also showing signs of cellulite as she strowd down Madison Avenue on a shopping trip.

And as she redied herself for New York's fashion week, Posh Spice also flashed her unsightly wrinkly thighs.

Perhaps the strain of performing with the Spice Girls in four-inch heels is getting to Victoria's slender legs.

Knees up: Victoria Beckham's legs caught the attention of onlookers for all the wrong reasons as she headed out for a shopping trip in New York

Her penchant for towering stilettos has already taken a toll on her feet - she was spotted with giant bunions while on stage last week.

Dressed in an elegant camel coat, black mini-skirt and knee-high platform boots, the 33-year-old cut a lonely figure as she shopped in Manhattan without her husband David, who is busy training in LA.

Along with a string of Spice Girls concerts, Victoria is hoping to attend Marc Jacobs' catwalk show while in the Big Apple. She is, after all, the new face of the popular fashion label.

Earlier this month, her group announced they were cutting their world tour short, blaming family commitments for the surprise decision.

Victoria said: "We have children who need to go back to school and we have always said our families are our priorities, so we want to thank all of our fans.

"Sorry we didn't get to see everybody. We had a great time."

Sources say the decision was in fact a result of a bitter rift that has formed between the group.

And the group did little to quell speculation about in-fighting earlier this week after arriving separately at Toronto airport - despite all leaving Canada for New York.

The famous five were also thought to be staying in separate hotels when they got there.

The Spice Girls will play their last date on February 26 in Toronto.
