Patrick Kielty has teased three guests for tonight's Late Late Show on the series' Instagram page.
Derry Girls star Nicola Coughlan, Spice Girl Mel B and singer Ronan Keating are all set to appear on this evening's show.
In the video, Kielty appears in a radio studio donning '90s style-clothing, announcing each guest with photos and clips in a '90s radio jock style voice.
He opens the video with, "This week on The Late Late Show, we're going back to the '90s with one of the biggest girl bands from Derry City," he says, over a clip of actress Coughlan performing as Spice Girl Emma Bunton in her breakout role on Derry Girls.

Next he says, "We're also going back to 1999 to this man who told us to ride it," while playing an audio clip of Keating's hit song Life is A Rollercoaster and showing footage of the Dublin man in his Boyzone days.
"And we're going back to 1996 and putting on our leopard-skin print for this pop princess," he then says, while playing footage of Mel B in the Spice Girl's Wannabe video.
The video finishes with Kielty reverting to his normal voice, saying, "I'll tell you what I want, can I just get out of this ridiculous gear? That's what I really, really want."
