Demi Moore was rushed to hospital last night to be treated for exhaustion. The 49-year-old actress, who has appeared increasingly frail in recent weeks, was taken to hospital by ambulance following a call to 911 just before 11pm last night. The star’s spokesperson said the actress is seeking ‘professional assistance’ after the stresses of recent months. However, showbiz website TMZ are claiming the actress is being treated for ‘substance abuse’. The news emerged as her young husband, from whom she is estranged, was pictured enjoying a beer as he partied with friends at a Bruno Mars gig in Brazil.
