Shane Lynch, of Boyzone, has accused American singer Taylor Swift of committing satanic rituals at her concerts.
The 34-year-old Style hitmaker is presently touring the world on her sold-out Eras tour, having recently played seven performances in Sydney and Melbourne.
But now Shane, 47, a Pentecostal born-again Christian, has targeted the celebrity and other artists who execute 'demonic' rituals without fans 'even noticing'.
He told Ireland's Sunday World newspaper: 'I think when you're looking at a lot of the musicians out there, a lot of their stage presentations are Satanic rituals live in front of 20,000 people without them knowing and recognizing.
'There will be a lot of hoods up, masks on, and fire rites.
'Even Taylor Swift, one of the world's most famous performers, has two or three separate demonic rituals to do with the pentagrams on the ground, as well as other things on her stage.
"But to many people, it's just art, and that's how they see it, unfortunately."
He also stated that he has stopped listening to hip-hop and Grime because of the 'hidden Satanic' messages and 'evil' concealed within 'the beats' of the music.
Taylor wears a cloak during the 'evermore' part of her Eras concert while dancing with backing dancers holding lanterns.
Taylor went viral earlier this month after flashing a hand signal that some mistook for 'the sign of the horns', a Satanic emblem.
During her act, she was singing her hit Cruel Summer when many observed the movement, resulting in further unfounded charges.
The global megastar gave her farewell Eras Tour concert in the city on Monday night.
