Kate Moss has stayed faithful to Storm Models ever since its founder, Sarah Doukas, spotted her as a 14 year-old at JFK airport in 1988.
But yesterday the agency announced that Moss is no longer on their books.
'After a successful 28 year relationship, Kate is moving her business in house, and we will continue to maintain an active involvement in our on-going deals for her,' they said in a statement.
The move suggests Moss is perhaps going to move her focus away from modelling and onto other areas.
In December 2015 she registered 'Kate Moss Interiors Ltd' at Companies House after successful refurbishing a luxurious house in the Cotswolds.
She also has the company names 'Kate Moss Agency Ltd', 'Kate Moss Management Ltd', and 'Kate Moss Models Ltd' registered - so perhaps her own modelling agency is even on the books. Only time will tell.
Moss's half-sister Lottie remains signed with Storm.
