New Details on Sinéad O'Connor's Official Cause of Death Revealed

More details are emerging on Sinéad O'Connor's passing. 

The "Nothing Compares 2 U" singer, who was found dead in her home last July at age 56, died of chronic obstructive pulmonary disease and bronchial asthma, according to her death certificate obtained by the New York Times July 29. 

Bronchial asthma and obstructive pulmonary disease are both chronic conditions that affect your lungs, with the latter causing restricted airflow and breathing problems, according to the World Health Organization. 

Back in January, the coroner had attributed her death to "natural causes" but did not provide details. 

O'Connor's passing was first shared by her family, who told Irish broadcaster RTE in a July 2023 statement, "It is with great sadness that we announce the passing of our beloved Sinéad."

Noting that her loved ones were "devastated," her family concluded their message by requesting privacy "at this very difficult time."

The following day, London's Metropolitan Police confirmed that they responded to a call about an "unresponsive woman at a residential address" and weren't treating her death as "suspicious."

Since then, many stars have paid tribute to O'Connor, with U2's Bono even attending the funeral held in her hometown of Bray, County Wicklow in Ireland.

Russell Crowe also honored the acclaimed singer by sharing a moving chance encounter he and friends had with her outside of a Dublin pub a year before her death. 

"In a conversation without fences," Crowe recalled in a series of July 2023 tweets, "we roamed through the recent Dublin heatwave, local politics, American politics, the ongoing fight for indigenous recognition in many places, but particularly in Australia, her warm memory of New Zealand, faith, music, movies and her brother the writer."

The Gladiator star took the opportunity to confess to her that she was one of his heroes. 

"We sat there the four of us and variously expressed the same thing," Crowe remembered. "What an amazing woman."

He added, "Peace be with your courageous heart Sinéad."

E! News reached out to a rep for London's Southwark Coroner's Court for additional comment but has not heard back.
