Passage 2 With a teeny waist， exaggerated breasts， icy-blue eyes， 21-year-old Valeria says she is the real natural deal.A real-life Barbie， that is. That’s what she claims anyway， but many people doubt to her claims.Whether she underwent plastic surgery or uses Photo shop remains unclear.On her blog， the model notes that she is the most famous woman on the Russian Internet because of her doll-like appeal.Hundreds of photos on her Facebook page show a wide-eyed， nearly fake-looking Valeria posing in a variety of outfits.
