Sinead O’Connor: Cause of Death, Controversies & More

There are few voices as instantly recognizable as Sinéad O’Connor’s — and even fewer careers that sparked as much debate, admiration, and misunderstanding, from her shaved head and haunting cover of “Nothing Compares 2 U” to tearing up the Pope’s photo on live TV. She refused to fit the pop-star mold, and this article traces the key events of her life, the real cause of her death, the controversies that defined her, and the feuds that still fuel conversation today.

Born: December 8, 1966, Glenageary, Ireland ·
Hit song: “Nothing Compares 2 U” (1990) ·
Died: July 26, 2023, London, England ·
Albums released: 10 studio albums ·
Cause of death: Natural causes (chronic obstructive pulmonary disease and asthma)

Seven key facts, one pattern: O’Connor’s life was marked by bold artistic choices and deep personal conviction that often put her at odds with the music industry and public opinion.

What was the real cause of Sinead O’Connor’s death?

Sinéad O’Connor died on July 26, 2023, at her home in London at age 56. The BBC News first reported her death, and the London Inner South Coroner’s Court later confirmed the cause as natural causes. According to a death certificate obtained by People magazine, the official cause was chronic obstructive pulmonary disease (COPD) and bronchial asthma, with a low-grade lower respiratory tract infection contributing. The coroner concluded its involvement in the case, ruling out foul play.

The cause-of-death revelation came about a year after her death, in late July 2024, when Rolling Stone UK published the death certificate details.

The implication: The official medical finding removed questions about foul play and shifted public focus back to her artistic legacy.

What did Sinead O’Connor do that was so controversial?

Why did she tear up the Pope’s photo?

The most defining moment came on October 3, 1992, during her performance on Saturday Night Live. After singing Bob Marley’s “War”, O’Connor held up a photograph of Pope John Paul II, tore it into pieces, and said “Fight the real enemy.” The act was meant to protest child sexual abuse cover-ups within the Catholic Church, as she later explained. The backlash was immediate and severe. Radio stations stopped playing her music, and she was booed at a Bob Dylan tribute concert days later.

“I’m not sorry I did it. I’m sorry for the pain it caused.”

Her criticism of the Catholic Church predated the widespread public acknowledgment of abuse scandals. According to ABC News, she was a longtime critic of the Roman Catholic Church long before the scandals became mainstream news. The PBS NewsHour notes that the protest became a defining controversy of her career.

The implication: The SNL moment cost O’Connor the commercial success she had earned, but it also cemented her as an artist willing to sacrifice fame for principle.

What is Sinead O’Connor’s religion?

When did Sinead O’Connor convert to Islam?

O’Connor was raised Catholic in Ireland but grew increasingly critical of the church. In 1999, she was ordained as a priest in the breakaway Latin Tridentine Church, a move the mainstream Catholic Church did not recognize. She later left that group and converted to Islam in 2018, adopting the name Shuhada’ Sadaqat (also spelled Shuhada’ Davitt). She began wearing the hijab and said she felt “at home” in Islam, as reported by ABC News. Her journey from Catholicism to Islam reflected her lifelong search for spiritual authenticity.

The pattern: Each shift in her spiritual life mirrored her broader refusal to accept institutional authority without moral scrutiny.

Why did Sinead O’Connor have no hair?

O’Connor’s shaved head became her signature look early in her career. In interviews, she explained it was a personal choice: she did not want to be marketed as a sex symbol or judged on her appearance. “I didn’t want to be a pretty pop star,” she said in a PBS NewsHour documentary. The decision protected her from the industry’s objectification and allowed her music and message to take center stage. It remained her trademark throughout her career.

The pattern: The bald look was not a gimmick — it was a deliberate rejection of the music industry’s expectation that female artists be visually pleasing first and artists second.

What happened between Miley Cyrus and Sinead O’Connor?

What did Sinead O’Connor say to Miley Cyrus?

In 2013, Miley Cyrus released the “Wrecking Ball” music video, which featured her naked and licking a sledgehammer. Sinéad O’Connor responded with an open letter on her website, warning Cyrus not to let the music industry exploit her for sex appeal. Cyrus hit back on Twitter, referencing O’Connor’s mental health history. O’Connor then wrote a series of open letters criticizing Cyrus’s response.

Years later, after O’Connor’s death, Cyrus expressed regret over the feud, calling O’Connor’s concerns “motherly.” In a Twitter post, she said, “I was a young girl and she reached out to me with motherly concern.” This acknowledgment came too late for reconciliation, but it highlighted O’Connor’s protective instinct toward younger artists.

What this means: The feud illustrates O’Connor’s pattern of trying to mentor young women in the industry, often in ways that backfired due to her own history and directness.

What did Prince do to Sinead O’Connor?

Why did Sinead O’Connor call Prince a devil?

Prince wrote “Nothing Compares 2 U,” and O’Connor’s 1990 cover became her signature hit. In her memoir Rememberings, O’Connor described a difficult encounter with Prince at his home, alleging he became physically intimidating and threw an object at her. She later called him a “demon” in interviews, saying “He wanted me to be his puppet.” Prince never publicly responded to her accounts, and the exact details of their encounter remain disputed. Prince’s estate later blocked use of O’Connor’s version of the song in the 2022 documentary Nothing Compares, as reported by People magazine.

“He was a demon. He wanted me to be his puppet.”

The catch: With Prince deceased and no direct testimony from him, the full truth of their relationship remains one-sided, leaving room for continued public speculation.

Is Sinead O’Connor LGBT?

O’Connor publicly identified as bisexual and spoke openly about her sexuality in interviews. She had relationships with both men and women, though she married four times, all to men. Throughout her career, she was a vocal advocate for LGBTQ+ rights, often linking her activism to her own experiences of being marginalized and misunderstood by the mainstream.

What this means: O’Connor’s openness about her sexuality was consistent with her broader refusal to conform to industry expectations — she did not compartmentalize her identity for public consumption.

Legacy and what lies ahead

Sinéad O’Connor’s legacy is no longer defined solely by the controversy she once endured. Posthumously, her music and activism are being re-evaluated as prescient rather than reckless. The documentary Nothing Compares (2022) — despite Prince’s estate blocking use of her signature song — helped reintroduce her story to a new generation. For fans and music historians, the task now is to separate the headlines from the human being: an artist who refused to be silent, even when it cost her everything. For the public, the choice is between remembering the tabloid headlines or listening to the songs — and the choice will shape how her story is told for decades.
