It was possibly their last outing as a family of four as Crown Prince Frederik and his wife Princess Mary took their children to the ballet.
Little Princess Isabella and Prince Christian watched intently as the production - The Tivoli Dream - got underway in Copenhagen.
The work bears special significance for the family as Queen Margrethe did the costume and set design for the colourful show.
Mary looked elegant in a long-sleeved black dress and knee-high boots. She's due to welcome twins in mid January.
