It was possibly their final outing as a family of four when 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.
The talented monarch was on hand and joined the performers on stage at the end to take a bow. And she couldn't resist venturing down into the audience to give a kiss to her grandchildren.
Mary looked elegant as always in a long-sleeved black dress and knee-high boots. And you couldn't miss her baby bump. She's due to welcome twins in mid January, though many commentators are saying the new arrivals could easily come way before that.
The Danish royal house has already confirmed that she will not be taking part in the traditional New Year's reception held at Christiansborg Palace.
She looks really pregnant now. That's a relief!
