Tom Cruise and Dame Joan Collins have been added to the star-studded bill for the Coronation concert taking place on Sunday May 7.
They'll feature in a pre-recorded sketch to celebrate the crowning of King Chares.
Meanwhile, Buckingham Palace published three new photographs of King Charles and Queen Consort Camilla on Friday ahead of the monarch's coronation on May 6.
The images were taken in the palace in March by society photographer Hugo Burnand who was official photographer for the weddings of Charles and Camilla Parker-Bowles in 2005 and of Prince William and Kate Middleton in 2011.
Charles and Camilla appear in the photographs sitting in front of a state portrait of King George V, who reigned from 1910 until 1936 and was the great-grandfather of Charles.
The release of the photographs forms part of the palace's stream of media events ahead of the coronation in London's Westminster Abbey.
The concert on May 7 will take place in the grounds of Windsor Castle in front of a crowd of 20,000 members of the public.
