Veteran supermodels Eva Herzigova, 36, Helena Christensen, 40, and Claudia Schiffer, 39, have proved that age is no object when it comes to looking stunning.The models wore just leather thigh boots and a saucy wink for the naked mag shoot.Claudia said it was the chemistry of the three old-school catwalk queens and photographer Kayt Jones that made the pictures so sexy."A great photographer doesn't stop you or give you boundaries. It's about flow and chemistry - you just go together like a wave," News of the World quoted her as saying.The trio, all with 1 Model Management, also posed for stunning individual pictures for contemporary style guide i-D - including one with just a handbag protecting Claudia''s modesty.An insider said: "These women are so universally beautiful that they can wear high fashion, arty wear or more commercial stuff. Or they can just go plain naked."
