Father Ted actor Ardal O'Hanlon is set to guest star in the new series of Derry Girls.
Cast member Saoirse-Monica Jackson, who plays Erin on the show, revealed the news to Radio Times.
She said: "Ardal O’Hanlon joins our family this year, which is brilliant."
O'Hanlon will play Eamonn, an "awkward, middle-aged mummy’s boy of the Quinn/McCool extended family", a release from Channel 4 said.

Nicola Coughlan, who plays Claire, added that Eamonn is "a real Irish stereotype".
She said: "I think it’s something that everybody will recognise, and he completely gets it so on the money.
"It was really surreal, just looking at him, because he’s such an iconic figure in Ireland, and he’s such a lovely man. He’s so good in it."
The actress later tweeted a link to the story and said she's "buzzing" about him joining the cast.
