Victoria Beckham did something this morning that would make most of us cringe. And no, we're not talking about walking in six-inch stilettos -- rather, the former Spice Girl unveiled a 20-foot version of her new ad for Emporio Armani Underwear at Macy's Herald Square in New York City. The image is from the Autumn/Winter 2009/10 advertising campaign, and shows Posh in a lacy bra and panty set, up against a wall.

Content to leave the flesh-baring to the inanimate banner, Posh covered up for the event in an Emporio Armani black fitted tuxedo jacket with black jet beaded shoulders and black Swarovski crystal beaded leggings. Naturally, she had on some fierce Emporio Armani black satin platforms with silver twist heels. Fans and customers were left guessing which intimates from the new Women's Underwear collection Victoria had on underneath.

We have to wonder, though, if this brought up a bit of competition in the Beckham household. After all, hubby David's Armani underwear ad was put on a 70-foot tall banner in San Francisco, and actually sent women into a full-on frenzy. The couple also posed together for the brand.

This isn't the first time we've seen a giant Beckham in pricey undies, and it won't be the last -- this campaign is part of a three-year deal Victoria inked with Emporio Armani, netting her a reported $17 million.
