'Poker Face' singer Lady Gaga has arrived in Rome to attend a gay rights parade, where hundreds of thousands will voice their defiance against the Vatican and Silvio Berlusconi's "backward" government.
A religious group calling itself 'Militia Christi' is planning a small protest at the Circus Maximus, where Lady Gaga is expected to give a short speech and reportedly sing her hit single 'Born This Way', which celebrates diversity.
But Catholic politicians have warned Lady Gaga, a vocal advocate of gay rights, against making provocative statements about the Pope.
"The gay world does not feel represented by someone who makes videos that offend Jesus," the Daily Telegraph quoted Rocco Buttiglione, the deputy speaker of parliament, as saying.
"If Lady Gaga attacks the Holy Father or the Catholic Church, millions of gay moderates will not recognise themselves in those comments," he said.
Carlo Giovanardi, a junior minister for family policy, dismissed the event as "a chance to mock the Holy Father, make fun of the clergy and those who dedicate their lives to others and dress up in all sorts of costumes".
"Maybe she is badly informed about our country since all the opinion polls prove that an overwhelming majority of Italians are against marriage between a man and a man and a woman and a woman," he added in regards to Lady Gaga.
