The Nothing Compares 2 U singer handed over the cash to tax collectors following an audit.

Revenue Commission officials calculated she owed over $100,000 (90,500 euro) in tax, plus interest and penalties.

The singer, who has a home in Bray, Ireland, appeared on a Defaulters' List of major tax settlements, which is published every three months by the Irish Government.

News of the tax settlement comes just a few months after Sinead sparked concerns for her health and welfare when she went missing in Illinois amid friends and family fears she was suicidal.

She was later found at a hotel near Wilmette and taken to a nearby hospital.

She also received medical treatment back in November (15) after leaving an angry suicidal note for her family.
