Kylie Minogue is to perform for the Queen at the Diamond Jubilee Concert.
She has been added to the bill of the show which will take place outside Buckingham Palace in June.
US chart veteran Stevie Wonder has also been newly Signed, Sealed And Delivered for the line-up of the June 4 concert - to be broadcast by the BBC.
Kylie - who has previously performed for Prince Charles - said: "I'm honoured to be invited to perform at the Diamond Jubilee Concert.
"To share the stage in front of Buckingham Palace with music legends including Paul McCartney, Stevie Wonder, Tom Jones and Elton John in celebrating the Queen's Diamond Jubilee is very exciting."
Stevie's addition will prompt speculation that he will perform his worldwide hit Happy Birthday at the show, taking place on the Queen's official birthday.
He said: "It's an honour to celebrate The Queen. It's an honour to celebrate Great Britain.
"The time is overdue that I meet Her Majesty."
