Daniel O'Donnell's wife Majella will give her first interview on Friday night's Late Late Show since her recent double mastectomy.
Tom Curran will also talk to host Ryan Tubridy about life after his partner Marie Fleming. Marie fought and lost a lengthy legal battle for the right to end her own life before she passed away at the end of last year.
Oscar-winning actor Richard Dreyfuss, film director and Monty Python member Terry Gilliam, and model Roz Purcell are also on the show.
The Late Late Show is on RTÉ One on Fridays at 9.35pm
