Giorgio Armani unveiled the first images of Megan Fox modeling for his Emporio Armani Women's Underwear campaign, but the 23-year-old Transformers actress isn't the first star to have the honor of appearing nearly naked on the designer's billboards.

Victoria Beckham -- alongside hubby David Beckham -- also stripped down to her skivvies this past year for Armani's Fall/Winter campaign.
