Posh Spice shows off more skin in new lingerie ad

The former Spice Girl unveiled her new 20-foot banner, from the Emporio Armani women's underwear advertising campaign for Autumn/Winter 2009/10, on May 6 at Macy's Herald Square in NYC.

The 35-year-old mother of three had once said that she had "saggy skin" and looked "really awful" naked.

But Posh took everyone by surprise when she modelled for Armani's spring/summer 2009 ad campaign, shot by fashion photographers Mert Alas and Marcus Piggott, with her footballer husband David Beckham [ Images ].

"It's an honour to have been selected by Mr. Armani to represent the Emporio Armani Underwear brand and to execute his vision with the incredibly talented team of Mert & Marcus," Us magazine quoted her as saying at the time.

Last year, David had posed for the designer in his briefs.
