United Kingdom, July 9 -- Sir Cliff Richard has led tributes to his "wonderful friend" Bonnie Tyler following her death at 75.

The Total Eclipse of the Heart hitmaker passed away on Wednesday (08.07.26), weeks after she was placed into an induced coma following emergency intestinal surgery in Portugal, and her old pal admitted the news had come as a shock.

Cliff, 85, shared a photo of himself and Bonnie on Facebook and wrote: "Another wonderful friend gone too soon. Bonnie's infectious zest for life entertained so many around the world, and to be a good friend to all, including me.

"It is shocking news to wake up to you this morning and I send my love to her family at this very sad time. RIP Bonnie.. Cliff".
