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 July 9.

Insiders tell the publication Nielsen has been fighting a serious alcohol problem for years. 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."
