"I just love my sister," 19-year-old Bella says, who can count 20-year-old Gigi Hadid
as her older sis. "My first memory with my sister was probably when I was really, really young, and I would be lying in my crib, and every day she would come and put a trash can down, and stand in front of it because she was small too. She was like, two. [She would] put her little hands over the side of the crib, and look at me while I was sleeping."
