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.
"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.
