RTE's Ryan Tubridy and Derry Girls actress Jamie Lee-O'Donnell have previously clashed over her age, following the recent controversy on the Late Late Show.
On last Friday's chat show, host Tubridy got into hot water after asking the 30-year-old star her age, a question which she felt was "misogynistic".
Jamie-Lee, who plays teenager Michelle in the hit Channel 4 sitcom, quickly shut down the line of questioning and said that he wouldn't have asked a male actor the same question.
