Teasing Friday's show, the Late Late said: "This Eurovision Holy Trinity will perform Loreen's Tattoo, hoping their rendition of Sweden's winning song in 2023 will channel the winner's energy."
On the night, Ireland's Eurovision entry will be chosen from - in alphabetical order - Adgy, Bobbi Arlo, EMMY, Samantha Mumba, NIYL, and Reylta.
"Joining Patrick Kielty will be the act that gave Ireland its highest-ranking position at Eurovision since 2000, Bambie Thug," the Late Late continued.
"Bambie will give their feedback on the six acts hoping to take Ireland to the Eurovision Song Contest Final in Basel, Switzerland this May.
"Joining Bambie on the panel will be Donal Skehan, a former Eurosong contestant in 2008.
"Donal, a self-confessed fan, will be 'double-crossing his heart' that one of our six finalists will get out of the semi-final and make it Ireland's eighth win.
"Dancing with the Stars judge Arthur Gourounlian takes up the fourth spot on the feedback panel.
"From the glittering dancefloor to the Late Late Show Eurosong stage, will Arthur be saying 'J'adore' to all six performances?"
More details will be announced shortly.
