Mary opted to wear a beautiful ivory and gold pencil dress by Maria Fekih.
The royal paired this with a Cartier love bracelet, a Judith Leiber clutch and Gianvito Rossi metallic glitter pumps.
The Crown Prince Couple's Prizes' has been handed over by the couple since 2004 in collaboration with the Bikuben Foundation.
Mary and Fred present these prizes to honour both foundations, organisations, upcoming designers and artists.
This week, four prizes were handed out during the show.
The Crown Prince Couple's Social Prize was given to the Association of Greenlandic Children.
Author Kim Leine received the Crown Prince Couple's Culture Prize.
The Crown Prince Couple's Cultural Stardust Prize went to film director Annika Berg, while Fundamentet in Aarhus was given the Crown Prince Couple's Social Stardust Prize.
Earlier this week, palace insiders claimed Mary and Fred's 14-year marriage was beginning to be "strained."
A body language expert even went as far as to say the troubled princess looked uninterested throughout the last several of her royal engagements.
“There are a lot of rumours of tension between Mary and Fred,” a source told New Idea.
“There are whispers running wild of a divorce or possible split, and it’s become very stressful for the whole palace – trying to work out what’s going on. The truth is that like any married couple, Fred and Mary are having a tough time of it at the moment.”
