The Zombie singer is facing three charges of assault and one of wilful obstruction of police following her arrest at Shannon Airport in Ireland in November (14) for allegedly attacking a crewmember during a flight.

The 43 year old's lawyer Bill O'Donnell appeared at Ennis District Court in County Clare on Wednesday (02Sep15) to ask for a three-month delay, saying, "My client is presently receiving ongoing medical treatment and presently receiving residential treatment hence her absence from court."

Judge Patrick Durcan adjourned the case until 16 December (15).
