Princess Mary and her twins Josephine and Vincent heads to Copenhagen Zoo for panda enclosure

Crown Princess Mary of Denmark enjoyed a family outing with her twins Prince Vincent and Princess Josephine as they attended Copenhagen Zoo.

The Australian-born royal had visited the zoo the previous day with her mother-in-law Queen Margrethe, 78, of Denmark.

And on Thursday, the 47-year-old mother-of-four made her second appearance for the official public opening of the panda enclosure with her eight-year-old twins in tow – and my, how they’ve changed.

Prince Vincent and Princess Josephine – who looks just like her mother – stepped out in matching jackets as they were all smiles when they posed for photographs.

The trio were all rugged up as they met two pandas named Xing Er and Mao Sun, which were gifted by China’s Chengdu Panda Base as part of a Danish and Chinese research project.

The Australian-born princess put on a stylish display at the event as she opted for a chic trench coat, retailed around $780 (£425).

Her brunette locks were blow dried into sleek curls – while she donned her usual glamorous makeup, including a smoky eye, bronzer and a glossy lip.

Surrounded by zoo-goers, the Danish family-of-three were pictured cutting the giant ribbon on the red carpet, followed by a tour of the new panda enclosure.

Their family day out comes just one day after Princess Mary the zoo with Queen Margrethe as the Danish royals were seated front row for the opening. 

Queen Margrethe opted for a sophisticated monochrome look for the occasion.

She took a lead role in the grand opening of the premises, which was opened to the public on Thursday, and offered her congratulations to the zoo. 

The royal paired an asymmetric cream coat with black leather gloves and matching earrings for the occasion. 

Queen Margrethe wore her tied back and added a splash of colour to her look with a vibrant red lipstick.  

Meanwhile, Crown Princess Mary, 46, stunned in a powder blue coat teamed with navy accessories as she joined her mother-in-law for the monumental event.

The gorgeous piece was eye-catching on a grey day, and she paired it with a patterned grey and black scarf.

The Danish royals engaged in conversation and appeared to take great interest as they toured the enclosure. 

Both made an impact as they visited the newly built facility which will welcome two pandas, named Xing Er and Mao Suni, as part of a Danish and Chinese research project. 

‘Congratulations to all of us. We now have two pandas in a fabulous enclosure that we can look at for many, many years,’ Margrethe said. 

The enclosure, which is in the shape of the Chinese Yin-Yang symbol, is set to open to the public tomorrow.  

Queen Margrethe offered her congratulations as she opened the panda plant at Copenhagen zoo, which will house two pandas that were a gift from China's president during a state visit in 2012

The pandas are to be separated and brought together again during the mating season. 

Xing Er replaced another male panda China, who was originally picked to go to Denmark after it was discovered he couldn’t procreate. 

China has lent out pandas as a sign of goodwill to fewer than two dozen nations. Any cubs born during the 15-year loan period are considered China’s.  

The bears are ‘national treasures of China and symbol of peace,’ the Chinese Ambassador to Denmark, Deng Ying, said Wednesday.

In February 2018, China loaned two pandas to Finland. Two others arrived in June 2017 at Berlin’s Tierpark zoo, where the first visitors were German Chancellor Angela Merkel and Chinese President Xi Jinping.

The best-known case of panda diplomacy was in 1972, when a arrived in the U.S., two months after President Richard Nixon’s trip to China, ending 25 years of isolation and tension between the two.
