Take Me To Church singer Hozier has admitted to being "mortified" after hearing that comments made by actor Stephen Fry are to be investigated by gardai under the blasphemy law.
The Co Wicklow musician was one of many to voice their concerns over the investigation into Mr Fry's comments during an RTE show in 2015.
At the weekend Independent.ie revealed that a garda investigation has been launched into the comments after a member of the public made a report.
"Christ on a bike. Mortified by this. Feel free to report TMTC [Take Me To Church]. Would you believe it's not about going to church," Hozier said online.
Mr Byrne was contacted by the Herald over the issue, but said it would be "inappropriate" to comment given an investigation is ongoing.
It is understood that Mr Fry will not be commenting for similar reasons. The law was introduced in January 2010 as part of the Defamation Act by then justice minister Dermot Ahern.
The maximum punishment for the offence is a fine of €25,000. The law prohibits the "publishing or uttering [of] matter that is grossly abusive or insulting in relation to matters sacred by any religion, thereby intentionally causing outrage among a substantial number of adherents of that religion".
During the show, comedian and actor Fry was asked what he would say if confronted by God at the pearly gates.
Mr Fry, an atheist, replied: "How dare you create a world in which there is such misery? It's not our fault? It's not right. It's utterly, utterly evil.
"Why should I respect a capricious, mean-minded, stupid God who creates a world which is so full of injustice and pain?" He went on to say that, if he was met by the Greek gods, he would accept them quicker because, "they didn't present themselves as being all-seeing, all-wise, all-beneficent".
He added: "Because the God who created this universe, if it was created by God, is quite clearly a maniac, an utter maniac, totally selfish."
