AceShowbiz - Marie Osmond's ex-husband Brian Blosil has fired back at scandalous new tabloid reports suggesting he physically abused the singer and sexually abused one of their seven kids. In a new National Enquirer expose, which features quotes from Osmond about her "living hell" during the nearly 20-year marriage, the publication reports Blosil attacked his wife, once throwing her down a flight of stairs.

The article also suggests Blosil is under investigation for physically and sexually abusing one of the couple's kids. In a statement Blosil says, "The allegations made by supposed and incredible sources made about me are absolutely untrue."

But the piece prompted reporters at news show Entertainment Tonight, where Osmond occasionally works as a correspondent, to dig around for more information and they discovered Blosil was investigated by Utah authorities in 2007 for a sex offense after questionable images were found on his home computer.

According to the show, Osmond and a minor were interviewed. The case was closed after police found no reason to continue their investigation. Asked for a comment on the National Enquirer and Entertainment Tonight stories, a spokesman for Osmond says, "She isn't commenting at this time."

However, the news show is running a past interview with Osmond, in which she states the end of her marriage is "very complicated", adding, "God does not expect us to sit in something that's destructive." The singer is expected to appear on Oprah Winfrey's daytime TV show next week. It is not known if she'll discuss the Enquirer story.
