London, Jan 15 : Former Spice Girl Victoria Beckham has followed in the footsteps of her husband soccer ace David Beckham, by stripping off for a series of saucy Armani underwear ads.

Victoria has posed for moody black and white snaps promoting Giorgio Armani underwear, and her look in the advert is inspired by 1950s cinema.

According to sources, Victoria worked hard on her body for 6 months to get the preferred look in the ad campaign.

"She wanted to do something she could look back on in years to come and say, `I wasn't looking bad for a 35-year-old mum of three," the Sun quoted a source, as saying.

"She is really proud of the pictures and David loves them too," the source added.

The pictures will be used in a worldwide Emporio Armani advertising campaign in the spring, along with a TV advert filmed at the same time.

"She is a stylish and intriguing woman," Italian designer Giorgio Armani said. (ANI)
