The new photos were taken in the Blue Drawing Room at Buckingham Palace

Adventurer Bear Grylls and Sir Tom Jones will join them in pre-recorded sketches to celebrate the crowning of the King and the Queen Consort.

New pictures of Charles and Camilla have also been released.

The photos were taken by Hugo Burnand, who was the official photographer at their wedding in 2005.

In one picture, the pair stand together as they pose in blue outfits, and then sit separately on blue and gold chairs in the other two.

The photos were taken last month in the Blue Drawing Room at Buckingham Palace.

The concert on 7 May will take place in the grounds of Windsor Castle in front of a crowd of 20,000 members of the public - as well as being broadcast across BBC television and radio.

Other names will appear in pre-recorded sketches that are being billed as revealing little known facts about the monarch - including former Strictly Come Dancing professional Oti Mabuse,

Winnie the Pooh will make an appearance that could match that of the Platinum Party At The Palace in 2022, where the late Queen shared tea with Paddington Bear.

The latest names join a billing that already includes Take That, Katy Perry and Lionel Richie, as well as classical acts including Andrea Bocelli and Welsh bass-baritone Sir Bryn Terfel.

Music acts Paloma Faith, Olly Murs, veteran rock guitarist Steve Winwood, Nicole Scherzinger of The Pussycat Dolls and Chinese pianist Lang Lang have been added to the line-up too, along with Nigerian singer-songwriter Tiwa Savage, DJ Pete Tong with his Ibiza Classics project, and the teenage winner of The Piano TV talent show, Lucy.
