Engelbert Humperdinck has tested positive for Covid-19.
The 84-year-old singer - who lives in Los Angeles - has asked his fans for their prayers after being told he has the virus, despite "nearly a year of an abundance of caution and care".
He began a series of tweets: "After nearly a year of an abundance of caution and care, Covid has caught up with us and found a way into our home.
"Now we must not let a positive result bring a negative mindset but I must say I could use your help in this department.
"We are asking for prayers, good energy, love and support to be sent our way."
