Ryan Tubridy will present the Late Late Show for the final time tonight.
He has been in the hot-seat of the world's longest-running live chat show for the past 14 years.
Tonight's show includes an interview with President Michael D Higgins and a special Toy Show reunion.
A trad super-group, including Andrea Corr, Sharon Shannon and John Sheahan, will be performing live.
Speaking on his Radio One programme earlier this morning, Ryan says he's bracing himself for some surprises:
have a big big night plan tonight, I think I know pretty much everything that's happening, they just said there's a bit of business here and bit of business there, which is code for we're not telling you, so we'll see."
