Dame Kiri Te Kanawa will sing the British national anthem to open a series of gala concerts at Buckingham Palace to celebrate the 60th anniversary of the Queen's coronation.
The soprano said she was "honoured and thrilled" to be part of the coronation festival and sing God Save the Queen for the monarch.
Dame Kiri said the three gala concerts in mid-July would be a wonderful celebration of the Queen's long reign.
"It will be a fabulous event and such a privilege to be in the gardens of Buckingham Palace for the concerts," she said from Vienna.
"I can't wait."
