Isabella Khairiah Hadid was born on October 9, 1996, at MedStar Georgetown University Hospital in Washington, D.C. Her father, Mohamed Hadid, is a Palestinian Jordanian real estate developer, while her mother, Yolanda Hadid (née van den Herik), is a Dutch former model. Through her father, Hadid claims descent from Daher Al Omer, Prince of Nazareth and Sheik of Galilee. She has an older sister, Gigi, and a younger brother, Anwar, both of whom are models. She also has two older paternal half-sisters; Marielle and Alana. Hadid and her siblings were raised on a ranch in Santa Barbara, California. The family moved to Beverly Hills after ten years.
As a teenager, Hadid was an equestrian and dreamed of competing at the 2016 Summer Olympics, although she competed in equitation, which is not an Olympic discipline. She was diagnosed, along with her mother and brother, with chronic lyme disease in 2012. After graduating from Malibu High School in 2014, Hadid moved to New York City to study photography at the Parsons School of Design. She suspended her studies to focus on her modeling career, but has expressed an interest in returning to school once she’s done modeling to branch out into fashion photography. Hadid has also expressed an interest in acting.
In 2016, she was voted “Model of the Year” by industry professionals for Models.com. Over the span of four years, Hadid has made twenty-seven appearances on international Vogue magazine covers.
Born in Washington, D.C. and raised in Santa Barbara, California, Hadid began her modeling career at the age of sixteen. She was signed to IMG Models in August 2014, and made her New York Fashion Week debut the following month. In 2017, Hadid broke the record for the most Vogue September covers in one year by appearing in five international editions (China, Spain, Brazil, Australia and Arabia).
