Princess Mary, 51, looks youthful as ever as she attends the EliteForsk Awards

Princess Mary celebrated her 51st birthday earlier this month. 

And the Australian-born royal looked youthful as ever on Monday as she attended the prestigious EliteForsk Awards in Copenhagen. 

Mary, who presented at the awards, was absolutely glowing as she greeted the  recipients. 

The brunette beauty has barely aged a day since since burst onto the scene in 2000, after famously meeting Prince Fredrik at the Sydney Olympics. 

The EliteForsk Awards, roughly translated into the Elite Research Prize, honours outstanding researchers of international acclaim.

It awards five people under 45-years-old 1.2 million Krone, which equates to around $2.5 million Australian dollars. 

Mary was elegant and stylish in a black embellished blouse and hounds tooth pencil skirt, and a coat draped over her shoulders. 

She opted for a matte makeup palette and her brunette tresses tumbled around her shoulders in soft curls.

The Danish Royal Family shared stunning portraits of Princesses Mary earlier this month to celebrate her birthday. 

Mary wasn’t the only birthday in the royal house, with her twins Princess Josephine and Prince Vincent also turning 12 in January. 

The Danish Royal Family have previously shared single photos of the siblings together for their birthday, the household decided to break from tradition this year.

Instead of holding a photoshoot for the occasion, the proud parents have released their children’s school photos – taken by photographer Jens Rosenfeldt.

While Prince Vincent is the spitting image of his father Crown Prince Frederik, Princess Josephine has also inherited her mother’s thick long hair.

Prince Vincent – who was born 26 minutes before his sister in 2011 – is dressed casually in a faded purple hoodie as he beams at the camera.

The twins are fourth and fifth in line to the throne and are currently attending the Tranegård School in Hellerup, Denmark. 

Their elder siblings Prince Christian, 17, and Princess Isabella, 15, are also enrolled.
