And the girl from Tassie dropped by Copenhagen's Vega concert hall to make her mark for International Women's Day.
The mum-of-four left her tiara and ball gown back at the palace, slaying in a pair of fitted leather pants, knee-high boots, teamed with a black jacket with pretty flower detailing.
Mary was all smiles as she stepped out to one Europe's biggest venues.
The gig was hosted by Sandie Westh and featured a range of phenomenal female musicians including Katinka, Mendoza and Barbara Moleko.
No doubt the mother-of-four was loving some time to just kick back and enjoy the solid tunes.
It has been an incredible busy year for the Tasmanian-born beauty.
In January, our favourite girl from Hobart dazzled as she attended Denmark's Fashion Week.
She then showed off her shutterbug skills during her family's annual ski trip to Verbier in Switzerland.
The photos were posted to the Danish royal family Facebook page, showing 11-year-old Prince Christian, nine-year-old Princess Isabella and six-year-old twins, Princess Josephine and Prince Vincent, grinning ear-to-ear on their family vacation.
