Gigi Hadid
Since her mother was model Yolanda Hadid, Gigi always had modeling in her genes. She was a baby model at age 2 and shot with Guess co-founder Paul Marciano when she was only a toddler. She appeared in Baby Guess campaigns but returned to her career in her teenage years. She signed to IMG in 2013 and skyrocketed after her December 2014 cover for Harper's BAZAAR.
