Here's the lineup for tonight's Late Late Show
This is sure to be an emotional watch.
Keelin Shanley's husband Conor Ferguson will be joining Ryan Tubridy for tonight's Late Late Show.
Conor, who lost wife Keelin to cancer earlier this year, will be in the studio to discuss Keelin's legacy as one of the most established journalists of her lifetime.
The former Six One presenter passed away in February of this year following a long battle with breast cancer. Her memoir, A Light That Never Goes Out, was published posthumously today.
After Conor's interview, there will be a special performance by the Hothouse Flowers in memory of the late RTÉ presenter.
Also joining Ryan on tonight's show is comedian and writer Sharon Horgan, who will be discussing her incredible comedies Catastrophe with Rob Delaney and This Way Up with Aisling Bea.
She'll also be chatting a bit about growing up on a turkey farm, because why not?
Elsewhere, Graham Norton will be landing down for a bit of chat after spending his summer in west Cork.
The much-loved presenter will be discussing his draw to the countryside, as well as how home has always been an inspiration for his novels.
Luke O'Neill will be giving a demonstration on mask wearing, and Gavin James will be singing his latest single, 'Boxes.'
The Late Late Show kicks off on RTÉ One tonight at 9.35pm.
