Leo Sayer has been forced to cancel a series of shows after becoming "very ill".
The 75-year-old singer has taken to social media to reveal that he's spent the last three weeks in hospital in Australia, meaning he's been unable to fly to the UK to perform a series of scheduled gigs.
Leo - who married his partner Donatella Piccinetti earlier this year - wrote on Facebook: "I haven’t posted anything publicly about this before but I couldn’t fly or make the recent shows in the UK as I became very ill just before the trip.
"I have been in hospital here for the last 3 weeks in Australia with kidney, bladder and prostrate complications.
"It all happened at the last moment, so it was too late to warn anyone. Many thanks to Butlins and Tony Denton for making replacement arrangements for these shows.
"I’m so sorry to have disappointed my fans but these things can happen to us 75 year olds! (sic)"
Despite this, Leo is making a good recovery and he intends to return to the stage in 2024.
The 'Show Must Go On' hitmaker - who has lived in Australia since 2009 - also thanked his fans for their "concerns and good wishes".
Leo's Facebook post continued: "I’m still in hospital now but well on the mend. I will take a necessary short break from activities and be back fighting for shows in 2024. - particularly my UK and Ireland tour next autumn.
"Thank you everyone for all your concerns and good wishes… (sic)"
