Miriam O'Callaghan paid a touching tribute to her colleague David McCullagh as he wrapped up his last ever episode of Prime Time.
He will move from the weekly current affairs programme to the daily Six One news next week.
As he signed off on Thursday night, O'Callaghan paid a surprise tribute to her "kind" and "caring" colleague.
"This is my last Prime Time as I'm joining the Six One news from Monday," said McCullagh, who had co-presented with O'Callaghan for the past seven years.
"It's been an absolute pleasure to work on this programme.
"Thank you to everyone on the team, to all our guests and, of course, to the viewers.
"So, one last time, from Miriam and myself and everyone on the Prime Time team, thanks for watching, stay safe and goodnight."
He was clearly not expecting what came next as O'Callaghan stepped forward.
"Well, just before we go, and he didn't know I was going to do this, Dave, but there's absolutely no way I could let the moment pass without saying a massive thank you to you from everyone on our Prime Time team," she said.
"Your brilliant journalism, your presenting skills, they've been central to our show's continuing success.
"But much more importantly, you've been incredibly kind, caring and a lovely coll- eague and everyone on the show loves you, particularly me. You'll be greatly missed."
McCullagh will present Six One with Caitríona Perry.
RTÉ appointed her and the late Keelin Shanley as the new faces of Six One in 2018 after hosts Sharon Ní Bheoláin and Bryan Dobson stepped down from their roles the previous year.
Shanley died last February following a two-year battle with cancer.
