Say, don’t I know you? That was our thought as we ogled one of the long-legged lasses who walked the runway at this week’s Victoria’s Secret Fashion Show in New York. She’s Cambridge-bred beauty Cameron Russell , whose mom is Robin Chase , co-founder of Zip Car. A graduate of the prestigious Commonwealth School - she’s quiet and athletic, we’re told - Russell’s been modeling since she was 16 and has appeared in the pages of Vogue and W, and in ad campaigns for Calvin Klein , Armani , and Yves Saint Laurent .
