David Beckham's A Big Boy on Giant Ad 6/19/08

Soccer hunk-turned-underwear model David Beckham is sure to stop the traffic in San Francisco, California after his sexy new Emporio Armani ad was unveiled on a massive mural on Wednesday (18Jun08).

Wearing nothing but Armani briefs, the buff England and L.A. Galaxy star shows off his fabled 'golden balls' while working out on a Malibu, California beach.

The revealing shot, taken by fashion photographers Mert Alas & Marcus Piggott was unveiled on a giant mural facing Macy's store in the heart of San Francisco at 5pm local time. The photo will also grace billboards in New York, Los Angeles, Rome, London, Milan, Paris and Tokyo.
