The end-of-season party at the Morrisson Hotel was held in advance of a summer inquiry by RTE chiefs into alleged bullying on the show.
Programme regular Trevor Keegan tried to quash rumours that there was any tension at last weekend's bash.
The former AA Roadwatch reporter was adamant the entire team were in great form at the private event at the Morrison hotel and, according to Trevor, "a great night was had by all".
He said: "Everyone from the team was there and, genuinely, there was a lovely atmosphere.
"I know people would want there not to be for some reason, but there were no issues. We all had a great evening. Richie Wilson, the head chef at the Morrison looked after us. He's a lovely guy and a regular on the show."
Station bosses confirmed the Afternoon Show would return for a sixth season, but have refused to reveal who will take the role of presenters.
Trevor claimed he is still in the dark as to whether he will be back on the show next season.
He said: "We've only been off a few days and you never know what's going to happen this early in the summer.
"I think they're still in the process of working it out.
"I make no secret of the fact that I love doing it. It's a great show and a great team but it's up to the powers that be.
"It was very flattering to be asked to do it but, obviously, I would have liked to do it under better circumstances."
Another party guest said the room fell silent when Sheana Keane arrived unexpectedly.
The guest said: "No one expected Blathnaid to turn up to the party, let alone Sheana. It was a complete shock when she arrived.
"Once everyone got over the initial surprise it was a great night, it was all very civilised."
Sheana Keane (33) took a leave of absence in March for "personal reasons".
She is officially suffering from vertigo.
However, claims emerged that the star had reportedly launched a bullying complaint against co-host Blathnaid.
The presenters and RTE have refused to comment.
