MARIE OSMOND's furious husband walked out on her in an explosive fit of rage after learning she was planning to dish all the sordid details about her abusive second marriage in her new tell-all.

Sources say Stephen Craig — Marie's first husband, whom she remarried in 2011 — blew up at the showbiz dynamo and is now demanding that she keep private the tawdry information about her troubled relationship with second hubby Brian Blosil.

"Steve left Marie," a source close to the family told The ENQUIRER. "He told her, 'I'm sick and tired of hearing about Brian and all your problems. We had an agreement that you weren't going to air your dirty laundry in public about your divorce.'

"The argument escalated and the next thing marie knew, Steve stormed out! "Marie was devastated. She really believed her marriage was over. Steve came back a couple of days later, but he's still angry. Whether or not their marriage will survive is a day-to-day question."

Marie's new book, "The Key is Love — My Mother's Wisdom, a Daughter's Gratitude," is scheduled for release in early April.
