Tonight's Late Late Show line-up will include Northern Ireland First Minister Arlene Foster, author Marian Keyes, two Holocaust survivors and "Mr. Eurovision" himself, Johnny Logan.

Foster, whose DUP party backed Brexit, will be in the studio for the first time with Ryan to discuss the UK's departure from the EU, as they officially leave at 11pm.

Marian Keyes will call in to lighten spirits a bit with a discussion of her latest work and trademark hilarious takes on everyday life and being a modern woman in a modern world.

Dublin-based Holocaust survivors Tomi Reichental and Suzi Diamond will discuss their chilling childhood in Auschwitz, 75 years after their liberation.

Now the 40-year anniversary of Johnny Logan's triumphant Eurovision glory with What's Another Year, the singer will be in the studio with a special performance of the track. The legendary songwriter who penned the track, Shay Healy, will also stop in for a chat.

Somebody's Child is slated to fill the second musical slot.
