Dailysnack.com quoted a hotel guest as saying: "Owen arrived with a friend and requested the private library room. He looked like he'd already been drinking. He was stumbling when he came in and literally falling down when he left."
Owen's representative denied the charges but another witness said: "They had bottle service and were drinking vodka. Owen got so drunk that he stumbled when he went to leave. He could hardly walk."
Wilson was hospitalised in August after he slashed his wrists and was reported to be suffering from severe depression and consuming inordinate amounts of drugs and alcohol. But these claims have been strongly denied.
A source said: "Owen's breakdown was treated as a mental health problem as opposed to a substance-abuse issue. So Owen's goal wasn't to sober up, it was to feel better about himself."
