The lineup for this week's Late Late Show Ukraine fundraising has been revealed.
This week's show, with the help of the Irish Red Cross, will fundraise for the humanitarian crisis currently taking place in Ukraine.
Ryan will chat to Ukrainians living in Ireland about the war in their home country and the concerns they have for relatives still living there.
Confirming the news that a fundraiser for Ukraine would be held, Ryan said: "We will feature Ukraine on the programme, we will endeavour to raise some money and maybe even morale for Ukrainians in this country and let them know that we stand in solidarity with them."
Also joining Ryan to help with the fundraiser is Dublin band, Aslan.
Singer-songwriter Roisin Murphy will also chat to Ryan about the war in Ukraine and how she recently cancelled two concert dates in Russia.
Scottish actor and one of the stars of The Good Wife, Alan Cumming will also share his thoughts on Russia's invasion of Ukraine.
A number of businesses around Dublin are still collecting supplies for Ukraine.
The Late Late Show will air at RTE One on Friday, March 4 at 9.35pm.
