Irish singer and songwriter Sinéad O'Connor has died at age 56, her family announced in a statement on Wednesday.

Jamie Lee Curtis dedicated a heartfelt Instagram post to the late singer: "I loved her. Her music. Her life."

"I once heard Sìnead sing acapella in an empty chapel in Ireland. It was under construction at the private home of our host," Curtis wrote in her caption. "It was one of the most beautiful things I've ever heard in my life."

"She was a warrior. She was a rebel. She ripped up a photograph that was on her mother's wall because of the hypocrisy of the abusive life she was raised in under the banner of the church," the 64-year-old actress continued. "Rest well. Rest in power. Rest in peace."
