DESIGNER to the stars Ozwald Boateng and his glamorous Russian wife Gyunel are to divorce. Twice-married Boateng, 41, who has a reputation as one of the best tailors in the country with a client list that includes Jude Law, Mick Jagger and Daniel Day Lewis, confirmed the split last night. The father of two opened his first store in London in 1993, setting up shop in Savile Row the next year. Gyunel, 31, a former model and a graduate of the London College of Fashion, shared her husbands passion for designing and modelled for him during her heyday. A family friend says: 'It has been a very difficult time for the family but Ozwald and Gyunel have said their marriage is over. Gyunel, who works for a number of charities, was understood to be away from their mansion flat in Londons Regents Park with their children, Emilia, six, and Oscar, three, last night. DM
