Sinead O'Connor died of natural causes.
The 'Nothing Compares 2 U' hitmaker was found dead at her rented flat in London on July 26 aged 56, and now the coroner has confirmed the late music legend's cause of death.
A spokesperson for Southwark Coroners Court told Express.co.uk: "This is to confirm that Ms O’Connor died of natural causes. The coroner has therefore ceased their involvement in her death."
Police did not treat her death as suspicious when she was found unresponsive.
The confirmation comes after her friend claimed she could have died from a “broken heart” after the death of her teenage son.
The Irish-born star was left devastated by the passing of her boy Shane by suicide at the age of 17 in January 2022.
O'Connor’s friend and producer David Holmes, 54, who was working with her on her final album at the time of her death, said in the new RTÉ documentary ‘Sinead’: “Even though Sinead was this incredibly resilient survivor, I totally believe that people can die of a broken heart.”
Belfast-born Holmes spent five years collaborating with O'Connor on what turned out to be her final album, ‘No Veteran Dies Alone’, after the pair met at the late Shane MacGowan’s 60th birthday celebration at Dublin’s National Concert Hall in 2018, where O'Connor performed alongside singers, including Nick Cave and Bono.
Holmes said about their meeting: “We ended up backstage. I just stopped and introduced myself and said, ‘My name is David Holmes, you probably have no idea what I do or anything about me but I would love to make an album with you about healing.’
“At that moment wasn’t a good time for Sinéad – everybody knows she had mental health issues.
“I needed healing myself. I was going through my own experience. It’s amazing what the right song or piece of music can do.”
Holmes and O'Connor ended up recording nine tracks together before her death.
Singer Christy Moore, 78, also appears in the new documentary on the singer, which aired on Monday, and tells how her death was a “terrible loss”.
The show covers the ups and downs and controversies of O'Connor’s life, including the row that erupted when she famously tore up a picture of Pope John Paul II live on American TV in 1992 in protest at the Catholic church’s cover-ups of child abuse.
