And my, how they grown up!
The eight-year-old twins joined their mum as she officially opened the new panda facility at the zoo.
Josephine and Vincent were all smiles as they rugged up from the chilly weather in navy jackets.
Vincent looked smart in a grey jumper and navy pants while Josephine accessorised her puffer jacket with jeans and lace up boots.
Meanwhile, Mary looked as glamorous as ever in a navy Fonnesbech trench coat and a pair of black suede boots.
The family were treated to a tour of the new panda enclosure that features two new pandas from China named Xing Er and Mao Suni.
The pandas are a gift from the Chinese Government on a 15-year loan basis and the gesture is regarded as a symbol of friendship between the two countries.
Mary’s visit to the zoo marks her second in two days. She also visited with her mother-in-law Queen Margarethe to view the enclosure the day before.
