Isabella Khair Hadid is an American model, signed to IMG Models in 2014. In December 2016, the Industry voted her "Model of the Year" for Model.com's Model of the Year 2016 Awards.

In fall of 2014, Hadid moved to New York City and began studying photography at the Parsons School of Design, signing to IMG shortly before.
