Who are the guests on tonight's RTE Late Late Show amid 1990s hints?

The latest episode of the RTE Late Late Show airs on RTE One television at 9.35pm this Friday night. 

The weekly line-up has been kept largely under wraps for the most part since the new series began last year.

In previous years, the RTE press office announced the full line-up 24 hours ahead of air time on Friday.

This time around, with new host Patrick Kielty at the helm, only a handful of guests have been officially announced ahead of time, including Jamie Dornan who was on the sofa recently.

Host Patrick Kielty this week has hinted at a 1990s theme, suggesting Nicola Coughlan from Derry Girls will be on the sofa. Ronan Keating and Mel B from the Spice Girls also look set to appear.

Producers are tight-lipped about the rest of the line-up this week so viewers have to keep a close eye on the RTE Late Late and Patrick Kielty's social media channels for some hints. Last week viewers were left guessing before an all-Irish line-up was revealed on Friday, including Tommy Bowe, Donncha O'Callaghan, Kayleigh Trappe and Karl Mullan.

Fans recently worked out that Conan O'Brien was on the show after Patrick Kielty posted a cryptic clue on social media. He was then also joined by Graham Norton on the sofa.
