In true Australian fashion the 46-year-old held the can of Carlsberg up as a toast, before taking a sip.
Wearing a stunning floral frock, her glamorous attire was a stark contrast to the beer pulling faces Mary made at the occasion.
The event was held to highlight Denmark’s achievements in sustainability. It’s not the first time Mary has attributed to this cause.
The royal who is originally from Tasmania has spoken about her thoughts on the subject in the past.
“I believe that in order to find solutions to some of the most pressing global challenges of today we need to take a holistic approach that requires us to consider the social, environmental and economic aspects and work together in new and innovative partnerships, maybe with people and organisations we wouldn’t have thought about working with before,” she told Vogue previously.
“It will require a continuous effort and patience, and strong and authentic leadership: it takes time to create real and sustainable change.
“I try, as effectively as possibly, to use the platform that I have built up over the years to advocate and work for the empowerment of women and of their human rights,” she said.
