( CM ) - The surrogate mother of pop superstar MICHAEL JACKSON's children is furious they have been pictured for the first time without their usual veil disguises. Debbie Rowe - who conceived ten-year-old Prince Michael I, and nine-year-old Paris through artificial insemination - was shocked last week (ends03Feb08) after photographs of her children unmasked and dressed in sneakers and baseball caps were published in newspapers around the world. And the 49-year-old - who divorced the Thriller hitmaker in 1999 after three years of marriage - insists the disguises are necessary to protect their offspring from kidnap threats. She says, "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."
