ITV presenter Holly Willoughby, who now fronts the new series of Blind Date – the dating show famously presented by Cilla in the 90s – also took to Twitter to honour her “hero”.

A book of condolence has been opened in her home city at Liverpool Town Hall.

The life of the entertainer was portrayed in an ITV biopic last year, which followed the story of the typist’s rise to fame.

Gina Robertson, from St Julians, told the Argus she had many fond memories of her aunt. “She willed herself to die”. Now reunited with her Bobby.

Managed at one point by Brian Epstein, her first single, “Love Of The Loved”, was written for her by John Lennon and McCartney.

At this time the cause of her death remains unknown.

It was this resounding TV success which was eclipsing her musical career, although she always said she preferred to be remembered for her songs than for anything else. She knew something we didn’t. It was only at 3am she realised she was going into early labour.

Her eldest son is understood to have jetted to Spain the day before the tragedy.

One possible theory is that the hot weather might have been a factor, according to BBC Madrid correspondent Tom Burridge. “If it be in television then so be it, but I’ve had my time”. I never expected anything like this, I thought Cilla would be around for ever. Overall, Black had eleven top ten hits in the United Kingdom between 1964 and 1971. “Rest in peace.'”. “Loved her shows growing up too!! Xx”. She said, “My father played the mouth organ, my mother and aunts used to sing, and it wasn’t unusual for families to get together and make their own music in the fifties”. “Loved her shows growing up too!! Xx”. “I think that would be so special”.

“It is very sad to hear the news”. I just wrote: ‘One of us.

British talent has paid tribute to Black since news of her death became public, including actress Joan Collins and The Beatles’ Ringo Starr.

“Before we made it, we appeared in panto with her in 1978 at the Liverpool Empire”.

“There’s no evidence to link Cilla’s death to any criminal act but police and courts generally like to keep an open mind on things”. But I knew she wasn’t very well.

She later told Radio Times she planned to age “disgracefully”.

She said in the May 2014 interview that she did not want to “linger” or be a burden on her family. “I was like a big brother more than anything”.

She quickly impressed the Beatles and others with her talent. That’s when I realised.

Black’s journey to stardom began at Liverpool’s famous Cavern Club, where she started work as a part-time cloakroom attendant.
