Singer-songwriter Melissa Etheridge said that O’Connor was “haunted all her life,” on Twitter and that her death “is such a tragedy.”

“Ireland has lost an iconic voice and one of our absolute finest, by a long shot,” mixed-martial arts star and fellow Irishman Conor McGregor said on Twitter. “Rest In Peace, Sinead you are home with your son I am sure.”
