The stunning model appears in the campaign for the designer's spring collection in images that were taken by Inez van Lamsweerde and Vinoodh Matadin at famous New York restaurant La Grenouille.
Jason said of Stephanie's involvement: ''I wanted to cast a strong woman with definite sex appeal for my spring collection which was partly inspired by Helmut Newton's provocative photographs. Stephanie came to mind as the perfect muse for this collection and the fact that she has worked with Newton just made perfect sense.''
And it seems the feeling is mutual with Stephanie telling WWD: ''He looks like a 20-year-old FIT student, but has the skill of a great couturier of the past.''
The campaign will run in spring editions of Love Magazine, Tank Magazine and Self Service, as well as outdoors in lower Manhattan during New York Fashion Week next month.
