In 1999, while he was showing off his collection at a trade show in Phoenix, he was telephoned by Trish Summerville, then stylist to Madonna, Christina Aguilera and Pink, who was styling the 'Lady Marmalade' video and wanted to use his jewellery. Assia flew to LA the next morning with half of the collection. Since then, both Pink and Aguilera have become clients and friends, while Madonna snapped up several of his bling rings, before, in 2000, asking him to design wedding bands for herself and Guy Ritchie. Whenever he and Assia have a free weekend together (which is not all that often) they head off to their eccentrically decorated Georgian house in Walmer, Kent. There, they adopt a lifestyle that's almost comical in its contrast to their normal jet-setting existence: they play cricket in the back garden with their ten-year-old daughter Nika, go rockpooling and prop up the bar at the local pub. 'I probably couldn't cope if I didn't have that safety valve,' says Webster.
