The couple and their children are due to watch rehearsals and meet some of the acts taking part in the celebrations including Welsh singer Bonnie Tyler.
Mrs Tyler was last week made an MBE in the Queen’s Birthday Honours for her services to music.
The royals will also meet weatherman Owain Wyn Evans who is best known for his role on the nightly news programme North West Tonight and The One Show.
The Cambridges and their children will then be introduced to a number of West End performers, Rubicon Dance Company and the Wales Youth Choir for Good.
Prince William will accompany his father the Prince of Wales the Platinum Party at the Palace, this evening. The father and son duo will address crowds of over 22,000, paying homage to her Majesty's 70-year reign.
The Queen is not expected to attend following her absence from the Service of Thanksgiving yesterday morning and the Epsom Derby this afternoon.
