O'Riordan and Bressie worked together for one season of popular talent show The Voice.

Musicians, high-profile figures and friends of the singer have paid tribute to her and spoke of her legacy in Irish music. Some of the names who have spoken about O'Riordan in recent days include Ellie Goulding, Annie Lennox, Duran Duran and Jim Corr.

Dolores O'Riordan (46) was found dead in the London Hilton on Park Lane hotel on Monday. She had been in the city for a short recording session.

Sharing a photo of them together, Bressie (Niall Breslin) said that he would "remember every conversation" he had with her.

"I will remember every conversation and every moment I was lucky enough to spend with this beautiful soul," he said.
