We've arrived to the final episode of the series, and Ryan has some seriously impressive talent joining him for such an occasion.

Joining Ryan on tomorrow night's 'Late Late Show' series finale will be President Michael D. Higgins. The pair pre-recorded an interview earlier this week during the fine weather, which was filmed at the gardens at Áras an Uachtaráin.

Two of Ireland's biggest exports will also be making appearances, with Saoirse Ronan and Colin Farrell both joining the show to talk about their successful careers in Hollywood of late. Saoirse was nominated for her fourth Oscar earlier this year for her role in 'Little Women', while Colin will play the Penguin in the new Robert Pattinson caped crusader revival, 'The Batman'.

Robbie Keane will discuss how his experience of the pandemic inspired him to fundraise for those working in hospitals around Ireland, and Sibéal Ní Chasaide will give a special performance dedicated to all those who have lost their lives during the crisis.

Ryan will also be paying tribute to all of the hardworking frontline staff across the country on Friday night. This season kicked off with an opening segment honouring Ireland's National Services back in September, not knowing how apt the piece would come to be. The presenter will catch up with some key workers from frontline services including nurses, doctors, nursing home staff, and paramedics who have played a vital role in recent months.

And finally, Sinead O'Connor will be returning to the studio once again for the series finale of 'The Late Late Show', having already appeared last September with an incredible performance of her track 'Nothing Compares 2U'.

Ryan said of this this season's series finale: "This season we lost Gay Byrne, such an iconic person in my life, professionally and personally.  We also had to say goodbye to Marian Finucane and Larry Gogan - all true legends of Irish broadcasting. It has been an emotional, difficult, poignant, and joyful season overall."

There will be all this and more as the 'Late Late Show' airs live tomorrow night on RTÉ One at 9.35pm.
