LATEST: Prince William's ex-girlfriend Kate Middleton has blamed the young Royal's father Prince Charles for the couple's break-up. The normally tight-lipped brunette, who works at UK fashion chain Jigsaw, blurted the reason for the split to worried work colleagues, saying, "It's because of his daddy." It is thought Charles advised his son to ditch his girlfriend unless he planned to marry her, to avoid the mistakes he made with Diana. Jigsaw co-worker Philip Higgs tells British newspaper Daily Mirror, "Normally, Kate doesn't talk about anything. She's very quiet. But it was as if she'd reached boiling point from one sympathetic question too many."
