Business as usual: no sign of maternity wear for stiletto-wearing Victoria Beckham

It's doubtful she'll ever be seen slouching around in UGG boots or tracksuit bottoms.

But four months into her pregnancy and Victoria Beckham shows absolutely no sign of breaking out the maternity wear.

The former Spice Girl, who's expecting her fourth child in summer, worked her usual high fashion look as she arrived at JFK airport.

There wasn't a baby bump in sight as she strode through in a pair of leather trousers and a loose fitting white top and jacket.

And ever present was her hallmark towering stilettos – this time a pair of black studded Christain Louboutins.

Drawing much comment was the item Victoria held in her hand - a gold plated iPhone worth £22,000.

The luxury accessory is adorned with 150 grams of 24 carat gold, and takes weeks to make, according to the website of its creator Stuart Hughes.

Victoria is yet to comment on reports that she's expecting a girl.

According to The Sun newspaper, a 16-week scan revealed the sex of the new baby, and Victoria wept tears of joy.

A source told the paper: "Victoria is 36 and David is thinking about life after retirement.

"For them, with a sister for their boys – who are growing up fast – this is the perfect family.

"All their dreams have come true. They couldn't have wished for more."

The couple are in Britain with their boys until the end of February as Victoria prepares her latest collection for London and New York fashion weeks.

Meanwhile, David is training with Tottenham Hotspur before returning to America for the start of the football season.

It's been reported that Posh will have her baby in the US, at the celebrity favourite Cedars-Sinai hospital.

It's thought she will have a c-section, as she did with her other three children.
