The Sports Illustrated Swimsuit Issue model has rekindled her romance with Simpson, nearly six months after their initial split.
The pair has been spotted out together over the past few weeks, including a stop at Miley Cyrus' birthday party in Hollywood on Saturday (22Nov14), and Hadid confirmed the reunion to HollywoodLife.com while on the red carpet at the American Music Awards the following day (23Nov14).
She said, "I am back with Cody, he is a great guys. I think the first time we were together, our schedules got in the way, but now we are taking the time to be together and make it work."
Hadid and Simpson initially split in May (14) after a year of dating.
