At the age of just 13, Kate's half-sister Lottie (back row, closest to Kate in photo) has been snapped up by a top modelling agency after being 'spotted' at her big sister's wedding to Jamie Hince, when she was a bridesmaid.
That's a year younger than Kate was when she was when she was identified by the same agent, Sarah Doukas, at New York's John F. Kennedy Airport.
Lottie recently had her first 'test' shoot with Storm Models and will have her career mapped out by the agency's bosses.
Her proud dad, Peter, told the Daily Mail: "It's early days, really. Storm, Kate's agent, felt that it was worth giving Lottie a test shoot and seeing how she turned out. She had a lovely time and she seemed to come out quite well, so everybody's happy so far."
As Lottie doesn't turn 14 until January, her development will be strictly controlled, but after that, expect her to storm ahead.
"If things work out for Lottie and she eventually gets some work, it could help her in the future," said her dad. "It's getting harder and harder to get jobs, university and things like that – so if she can get a couple of jobs early on and get something behind her, maybe it makes life easier."
It is believed that legendary photographer Mario Testino, who was the official Vogue wedding photographer, is already being lined up to shoot the promising starlet
And fashion soothsayers are clamouring to praise her. Carole White, the founder of Premier Models, who launched Naomi Campbell's career, said: "Lottie looks beautiful and fresh – a very English rose look."
Lottie already models vintage clothes for the Peter and Inger's store in West Sussex. But if the experts are right, it won't be long before she's on the catwalk to fame and competing with her big sister's £48m fortune.
