"After a successful 28 year relationship, Kate is moving her business in house, and we will continue to maintain and active involvement in our on-going deals for her," a spokesperson for Storm told the Daily Mail.
Moss was first discovered by Storm Management founder Sarah Doukas at JFK airport in New York when she was just 14 years old. She signed to the agency, and the rest of her prolific modelling career is history.
As for Lottie Moss, Kate's younger half-sister, she will continue to remain with Storm Models.
