Bray-based singer Sinead O'Connor is taking on Miley Cyrus with the kind of fervour she previously reserved for the Pope.
The now infamous war of words continues, with Miley's attacks generally contained within 140 characters on Twitter and Sinead's far more than that.
O'Connor started it with the first of many open letters, which she insisted was written 'from a place of motherliness and love.'
By now we all will have read at least the first letter, in which Sinead warns Miley not to allow her talent to be masked by stunts like appearing naked in her music videos.
She explained to the younger star that the music business is harsh and the executives making money off her do not care about the singer.
Cyrus had previously said that her video was partly inspired by Sinead's 1990 'Nothing Compares to You' video, which is why the Irish singer felt she was entitled to write to Miley.
Miley responded by taking to Twitter and mocking Sinead, reposting screenshots of years-old tweets Sinead had posted when she was feeling suicidal.
TD Alan Farrell waded in after O'Connor's appearance on last Friday's Late Late Show, with a tweet calling Sinead 'mad as a brush.'
He has since apologised following another open letter by the Bray resident.
O'Connor has now penned a fourth letter to Cyrus and demanded an apology for Miley's attitude towards mental health issues.
'You're entitled to have told me to go f*** myself if u liked [sic],' wrote Sinead. 'But to respond to it in a way that has caused so much personal harm and damage to me and to people who may struggle currently with suicidal feelings.'
