Prince Charles and Camilla Parker Bowles have been out in public together for the first time since announcing they are getting married.
They hosted a dinner at Windsor Castle on Monday night, and Camilla showed off her new diamond engagement ring.
The happy couple posed for snaps and said they were "absolutely delighted". And Mrs Parker Bowles added: "I'm just coming down to earth."
The wedding will take place at Windsor Castle on 8 April this year.
The Queen and Duke of Edinburgh said the news had made them "very happy".
Prince Charles' sons Princes William and Harry said they are "very happy" and wish the couple "all the luck in the future".
The Prince of Wales, who is the heir to the throne, was previously married to Princess Diana, who died in a car crash in Paris in 1997.
Camilla will be called HRH Duchess of Cornwall. She won't be Queen if Charles becomes King, but Princess Consort.
The marriage is a sensitive issue because Mrs Parker Bowles is divorced and her former husband is still alive.
If he became king, Charles would be the supreme governor of the Church of England, and some people in the Church are against the remarriage of people who are divorced.
