Fr Sean Hyland is set to appear on tonight's Late Late Show.
He will be speaking to Ryan Tubridy about his bestselling memoir Whisperings of My Soul.
It has been on the bestsellers list with Veritas each month since its launch last December.
"I want to sincerely thank all the parishioners in Kildare and Leighlin Diocese, Bishop Denis, all the parish teams and all of my fellow priests who have been so supportive in helping to spread the lovely heavenly blessings detailed in Whisperings of My Soul," Fr Sean said this week.
In an interview with the Offaly Independent recently, Fr Sean revealed that he has received proof that heaven and God exist.
The curate in Rhode and Clonbullogue, started studying for the priesthood in September 2010 at the age of 62, less two years after the death of his wife Liz from cancer.
