PRINCESS Kate and Prince William must travel to the US to "show who the real stars are," a royal insider has claimed.
The unnamed insider told royal biographer Angela Levin how Meghan and Harry are "more liked in America than the UK".
And they claimed that could damage "the whole monarchy".
Writing in her new book, Camilla, Duchess of Cornwall: From Outcast to Queen Consort, Angela Levin quotes the source as saying: “The Sussexes are more liked in America than in the UK, which can damage not only Charles and Camilla but the whole monarchy.
"The American issue has to be dealt with.
"The Cambridges have to go to the US to show who the real stars are.
"As will the Queen Consort and King Charles.”
Harry and Meghan moved to the US after stepping back from their royal duties in 2020.
They have since gone on to make a number of public claims against the Firm, with their bombshell Oprah Winfrey aggravating tensions.

Prince Harry's bombshell memoir is also on the way - but Angela Levin said she was told there are "several options" for the Duke and Duchess of Sussex's relationship with the royals.
In an extract of her book, serialised in The Telegraph, she said: "One is to hope that 'interest in what the couple say fades away'.
"Other options suggested were to 'shrug off' any harmful comments Prince Harry might make or 'try to privately negotiate some kind of ceasefire. But that is unlikely to work if Meghan just wants to win.'"
She added an "important alternative", however, is to "keep America close".
It comes after Prince William was due to co-host The Earthshot Prize Innovation Summit in New York City on Wednesday.
