Cliff Richard has moved to New York because he likes the "anonymity" of America, his friend Gloria Hunniford says.
The pop star, 78, has previously told how the trauma of BBC coverage of the police search of his Berkshire home in 2014, following a claim of historical sexual assault, had left him emotionally drained.
Richard was not arrested and charges were never brought, and he won a privacy case against the BBC last year.
However, Richard has now chosen to leave the UK for good, with Hunniford telling The Sun newspaper: "Cliff won't come back and live here.
"He has made that jump now. He was very disillusioned with what happened."
She said he "likes the anonymity in America", adding: "Some people recognise him but he does not get it all the time like he does here."
TV presenter Hunniford, a long-time friend of Richard, said he "loves coming back to perform occasionally and is looking forward to playing summer shows this year".
But she said she does not think he will ever return to live in the UK full-time again.
Richard has previously spoken of how the 2014 raid and the following legal battle took a toll on him.
In November, he told LBC: "I think most people know that what I have been through has been pretty traumatic emotionally.... It's been horrible.
"I finally feel that I came out of that mud and mire, and I'm here again and I'm doing what I'm best at really and what I enjoy most.
"So, if I do sound more excited, it's probably because I am."
The singer sued the BBC over the coverage and in July last year the judge ruled in the singer's favour, awarding him STG210,000 in damages.
A spokesman for Richard said: "There will not be any comment on what is essentially a private matter other than to confirm Cliff's main home is in Barbados, as it has been for many years."
