O'Callaghan is one of the most loved radio presenters in Ireland and her working life reflects this in a near-constant stream of opportunities, programs and personal tasks.

This year, she has announced that in order to accommodate her professional life she will not be hosting her summer chat show this year.

"I have too much to do and too little time", she reveals in an interview with RTÉ Guide. "I will be busy with the referendum up to June and then we have the visit of Pope Francis in August and then this documentary" - a documentary to mark the 50th anniversary of the Troubles in Northern Ireland.

"But I will be back with my chat show next summer."
