Middleton, now the Duchess of Cambridge, will be at the rural estate with her husband, Prince William, and other senior royals, including Prince Philip, the queen's husband, Prince Charles and his wife Camilla, and Prince Harry.
The queen will also deliver her prerecorded Christmas message that will be broadcast throughout much of the world.
Palace officials said Friday the family will mark Christmas with a church service on the estate grounds.
The queen is preparing to mark her Diamond Jubilee year marking 60 years on the throne. Extensive celebrations are planned.(
