Pop star-turned-doll maker Marie Osmond has launched a personal crusade to clean up the Internet after learning her two teenage daughters have been posting sexually explicit correspondence on their MySpace.com websites. The PAPER ROSES singer felt compelled to give a statement to US tabloid National Enquirer after the publication uncovered outrageous content on her daughters JESSICA and RACHAEL's blogs. On her site, 18-year-old Jessica, who was adopted by Osmond as an infant, claims she is a bi-sexual who craves sex "as many times as possible," while her 16-year-old sister describes herself as a "slut" and a "whore" in correspondence and opened up about her dreams of having sex with David Bowie. In her statement, shocked Marie, a devout Mormon, says, "I am saddened by some of the choices that two of our children have made. "The insidious potential for harm from adolescent Internet sites like MySpace.com only exacerbates these kinds of problems. "If my being a celebrity figure is good for anything, let it be as a voice of warning to other parents that no matter how protective we think we may have been with our children in the past, we need to become more knowledgeable and even more vigilant now in order to protect them."
