Sinéad O'Connor's official cause of death has been confirmed, one year after the singer died at age 56.

O'Connor died from chronic obstructive pulmonary disease (COPD) and bronchial asthma in July 2023, The Irish Independent reported, citing her death certificate.

The "Nothing Compares 2 U" singer also suffered from a respiratory tract infection, which contributed to her death.

O'Connor's former husband, John Reynolds, reportedly registered her death certificate in London Wednesday.

O'Connor was found unresponsive in her London home on July 26, 2023. She was later pronounced dead.

At the time, British police said the Grammy winner's death was not being treated as suspicious. The coroner's office took over the investigation to determine her cause of death.

London's Southwark Coroners Court later announced in January that O'Connor died of natural causes.

The musician struggled with mental illness and once confessed to attempting to kill herself at least eight times.

In early 2022, O'Connor was dealt another blow after her 17-year-old son Shane died by suicide.

Less than two weeks before her own death, O'Connor posted a heart-wrenching tweet mourning her late son.

"Been living as undead night creature since," she wrote alongside a photo of her hugging Shane. "He was the love of my life, the lamp of my soul."

"We were one soul in two halves," she added. "He was the only person who ever loved me unconditionally. I am lost in the bardo without him."

O'Connor is survived by her three other children.

Meanwhile, the confirmation of O'Connor's cause of death came as a wax figure of the later singer was unveiled at Dublin's National Wax Museum to mark the one-year anniversary of her death.

However, the wax figure immediately received backlash, with O'Connor's brother John claiming that it did not resemble his late sister at all.

"It looked nothing like her and I thought it was hideous," John told RTé's Liveline.

Following the criticisms, the museum announced via a statement to the BBC that it decided to remove the wax figure of O'Connor and create a new one.

The museum said that O'Connor's impact was "immeasurable," so it hopes to create a figure for her in the "most fitting and respectful manner."

"With this in mind, we are committed to creating a new wax figure that better reflects Sinéad O'Connor's true spirit and iconic image," the museum said. "Our team of skilled artists will begin this project immediately, ensuring that every detail is meticulously crafted to celebrate her legacy appropriately."
