Sylvester Stallone's statuesque ex-wife Brigitte Nielsen has checked into rehab in North Hollywood following a family intervention. New husband Mattia Dessi was among those who begged the Danish model/actress to seek help for alcoholism, according to the National Enquirer. Nielsen reluctantly checked into the Cri-Help facility on 9 July (07). Insiders tell the publication Nielsen has been fighting a serious alcohol problem for years. She appeared drunk on American reality TV show The Surreal Life in 2005. A source says, "It took an ultimatum from her family to get through to Brigitte - either she gets help or she loses her loved ones' support." Nielsen's manager, Ryan Glasglow, confirms the actress is in rehab, stating "Brigitte's getting the help she needs and has a positive attitude about her recovery."
