In 2012, James was selected to compete on the nineteenth cycle of America’s Next Top Model. In the competition she was one of the front-runners, receiving three first call-outs as well as winning three challenges for her scholarship bank. She appeared in the bottom two three times. In Jamaica, James landed in the bottom two with Kiara after the Dream Come True photoshoot for their weak photographs but in the end, James had the higher score, leaving James to compete alongside fellow contestants Leila Goldkuhl and Kiara Belen in the finale.
