"This is to announce that I am proud to have become a Muslim," he wrote on Twitter on October 19. "This is the natural conclusion of any journey of an intelligent theologian, and every study of the Scriptures leads to Islam, which makes all other Scriptures redundant."
The singer added: "They will give me (another) new name, it will be Shuhada & # 39;".
She spells her new name, which means "martyrs" in Arabic, with an apostrophe at the end.
The singer of "Nothing Compares 2 U" has replaced her Twitter profile photo with a photo that says "Wear a hijab, just do it" along with the Nike logo.
Her recent publications have included her singing the Islamic call to prayer, the Azan, and representing her wearing a hijab.
The 51-year-old woman has tweeted that she is "very, very happy" and apologized for mispronouncing some words in Arabic during her recitation of the Azan.
Although his embrace of Islam attracted anti-Islamic criticism and comments, it was widely welcomed by other Muslims online.
"Salaam (a greeting that means" peace ") and continues the good work," said Immy Khan. "You have 1.7 billion brothers and sisters now."
On Thursday, Davitt tweeted: "Thank you so much to all my Muslim brothers and sisters who have kindly welcomed me to the Ummah (the Muslim community) on this page today … You can not begin to imagine how much your tenderness means to me. "
The singer formally known as O & # 39; Connor made headlines in 1992 when she took a photo of Pope John Paul II during an appearance on a US television show.
The Catholic Church dismissed the singer's ordination at that time as "strange and absurd."
She called the Vatican "a nest of demons," which called for the creation of an "alternative church," and lamented that "liars murder Christ" in the Vatican.
The following year, O & # 39; Connor was reported missing in Chicago when she did not return from a bike ride, but police found her a day later.
Last year, she posted a tearful video of herself about her mental illness, which sparked concern among friends and family.
The images show her crying in a motel room and they complain that her family has abandoned her because of mental health problems.
"People who suffer from mental illness are the most vulnerable people on Earth," said O & # 39; Connor. "You have to take care of us, we're not like everyone."
