Using hidden cameras, a journalist from Panorama magazine - owned by Italian Prime Minister and media baron Silvio Berlusconi - filmed three priests as they attended gay nightspots and had casual sex.
Today there was no immediate comment from the Italian Bishops Conference and the Vatican - which has been rocked by a series of sex scandals involving paedophile priests since the start of the year.
The article describes how the reporter was assisted by a gay 'accomplice' as they 'gate-crashed the wild nights of a number of priests in Rome who live a surprising double-life.'
In it's preview, Panorama added: 'By day they are regular priests, complete with dog collar, but, at night it's off with the cassock as they take their place as perfectly integrated members of the Italian capital's gay scene.'
The Catholic Church forbids priests to have sex and homosexuality is also seen as a 'sin' .
