Ryan Tubridy may be struggling with his listenership figures at 2fm, but he has found huge success at the BBC where his super-sub stint has seen more than six million people tune in.
Tubridy was filling in for Simon Mayo on his afternoon show on BBC Radio 2 for the past two weeks.
Lewis Carney, head of programmes at the station, said he is delighted with Tubridy's audience.
"Ryan has been a huge success sitting in for Simon Mayo on Radio 2's Drive Time Show," he said.
"He's brought his infectious warmth and humour to our airwaves and engaged the audience with his excellent presenting skill.
"We are absolutely delighted, and so are our listeners."
Radio 2 is currently edging ahead of its rival Radio 1 in the ratings with a record 15.6 million listeners in the first quarter of this year, according to audience figures.
Graham Norton's Saturday morning show on BBC Radio 1 drew 4.3 million listeners while weekday breakfast DJ Nicholas Grimshaw dropped to 5.85 million.
Tubridy's BBC listenership is in stark contrast to his 2fm ratings - he was recently beaten by former Westlife star Nicky Byrne's show.
The Late Late Show presenter slipped in the latest JNLR figures after losing 4,000 listeners.
His total listenership now stands at 144,000 - 1,000 less than Byrne, whose show with Jenny Greene took a slight dip from 151,000 to 145,000.
Speaking about Tubridy's continuing slide at 2fm, station boss Dan Healy said: "Ryan's ratings are still strong. Shows in a three-hour slot always perform stronger than those in a two-hour slot. That's why Nicky is ahead.
"We still have total faith in Ryan as a broadcaster."
RTE has denied recent reports that Tubridy was being moved to Ronan Collins' slot on Radio 1.
A statement issued via the 2fm Twitter account said: "There are no plans to move Ryan Tubridy from 2fm. Ryan Tubridy will be on 2fm in the new season."
This was followed by a statement from RTE Radio One, which read: "Ronan Collins hosts the number 1 music show in the country on @RTERadio1. His top radio programme will continue on Radio 1 in the new season."
