Camilla does a Di for Charles.
It is the latest in a series of occasions where Charles and Camilla have appeared together, as their relationship becomes more and more public.
Camilla attended the Queen's Jubilee pop concert at Buckingham Palace earlier this month, where she sat in the royal box close to Charles's sons William and Harry.
She was also at Buckingham Palace for the BBC's classical music concert Prom at the Palace a few days before. But although she was again sitting in the royal box she was carefully placed to sit next to Sir Michael Peat, keeper of the Privy Purse, and well away from both Charles and the Queen. Camilla and Charles's friendship has spanned more than 30 years, and is gradually becoming more accepted by the public and the Royal family.
