The official statement, released on Thursday morning, continued: “We will issue a further statement shortly but for now ask for privacy to deal with this tragedy.”
Welsh Secretary Jo Stevens has paid tribute to the singer following her death.
“So sad to hear of the death of Bonnie Tyler,” she wrote in a post on X.
“A Welsh music icon, Grammy and Brit award winner and the sound of my teenage years.”
Rhun ap Iorwerth, the First Minister of Wales added the singer was a “true icon”, and that he was “deeply saddened” by the news.
Tyler had been due to perform at the Sunshine Festival in Worcester this summer, along with a number of European dates.
She had also been booked to sing at Cardiff’s Utilita Arena on 17 December.
Family friend Owen Money told the BBC the singer “was one of those ladies who just loved life”, and he was “in disbelief” at the news of her death.
The musician and radio presenter said: “I’ve known her since before she was famous, in the late 60s when she was starting out in Swansea.
“She’s like family really. I was up her house last summer and the first thing she did was open a bottle of champagne.
“Not only were we friends but we were fans of each other. She was still huge in Europe, Germany, Holland, she was just so good. She’s a Welsh icon.”
