Singer Sinéad O'Connor, who became as well known for her remarkable music as her personal struggles, has died, according to RTE, Ireland's public broadcaster.
She was 56 years old. No cause of death was immediately available.
O'Connor's first album, "The Lion and the Cobra," was released to critical acclaim in 1987, but it was her 1990 sophomore album, "I Do Not Want What I Haven't Got," which broke her through as a well-known artist.
Her rendition of the Prince song "Nothing Compares 2 U" shot to No. 1 in 1990 and was nominated for multiple Grammys.
In the years following, O'Connor was embroiled in controversy, once ripping a photo of the pope on "Saturday Night Live." She later became a priest of a Catholic group and took to social media to air personal problems and outbursts.
In recent years, she was open about her struggle with addiction and mental health. Her 17-year-old son Shane died in 2022.
