Talk show host Marie Osmond and her music producer-husband, Brian Blosil, have separated after 13 years of marriage and seven children (four of them adopted), Osmond confided to Larry King, who broke the news in his USA Today column. "We hope the media will respect our privacy during this period of our lives," Osmond said in a statement released Monday. Blosil was Osmond's second husband. She revealed in October that she was suffering from severe postpartum depression after giving birth to her son, Matthew, in July. Shortly after the birth, she said, she handed the baby over to a sitter and took off up the California coast.
