Scary! Victoria Beckham Exposes Ribcage in Bold Photo Shoot

Victoria Beckham is channeling her days as Giorgio Armani's underwear model in her new shoot with Chinese Harper's Bazaar.

The mom of four bares skin -- and her ribcage -- in the photos shot by famed photographer Chen Man. In addition to her cleavage-baring ensemble, she also shows off fiery red hair, dramatic makeup and feathered eyebrows.

Although Beckham is known for being thin, the 37-year-old recently revealed how she maintains her waif stature, despite having given birth to her and husband David Beckham's four children, sons Brooklyn, 12, Romeo, 9, Cruz, 7, and daughter Harper, 8 months.

While dining at Il Pastaio in Beverly Hills last month, an onlooker tells Us Weekly about the star's eating habits. "All I saw her eat was arugula -- not even any salad dressing!"
