British royals PRINCES WILLIAM and HARRY will invite 200 children to celebrate their late mother DIANA, Princess Of Wales' birthday in London this summer (07). The young royals will dine with ailing kids helped by the Well Child charity in Wembley, west London on 30 June (07) - the night before their star-studded concert at Wembley Stadium, to mark what would have been their mother's 46th birthday. A spokesman for the Princes' London residence Clarence House, says, "William and Harry wanted to hold this lunch to celebrate the work of two very important organisations and meet some of the remarkable children."
