(digitalspy.co.uk) - Michael Jackson's ex-wife is fuming after the couple's children were pictured without wearing a disguise.Prince Michael, ten, nine-year-old Paris and Prince Michael II, five, were photographed with their faces exposed last week after a visit to see a ventriloquist in Las Vegas.The trio's heads are usually hidden with scarves, veils and shawls when they venture out in public.Debbie Rowe, who conceived the pop legend's two eldest children, said she was shocked after seeing the pictures in the press. She told the Daily Mail: "The veils were my idea, not Michael's. I had kidnap threats when they were babies. I did not want them to be recognised. I'm not happy they've been photographed without the veils." The 49-year-old claimed that she had "loved [Jackson] so much" during their relationship, adding: "He was my first serious boyfriend - and it still hurts."The couple divorced in 1999 after three years of marriage.
