Princess Kate and Queen Camilla stunned in tiaras as they arrived at Buckingham Palace for a glitzy reception.

The event, hosted by King Charles and Queen Camilla, is an annual reception to honour the members of the Diplomatic Corps.

The reception celebrates one of the largest Diplomatic Corps in the world and will see the King and Queen meet representatives of several countries.

The Princess of Wales is believed to be wearing the Cambridge Lover’s Knot tiara while Camilla was spotted wearing the Girls of Great Britain and Ireland Tiara.
