King Frederik and Queen Mary were joined by two very special guests on their royal visit to Greenland – their 13-year-old twins, Prince Vincent and Princess Josephine!

The youngsters were not included in the official itinerary for the Danish king and queen's tour, which ends on 6 July, and so it was a pleasant surprise as Vincent and Josephine joined in with the engagements.

The twins joined Frederik and Mary on a boat trip to Qeqertarsuaq, where they helped to install a new whale microphone for scientific Arctic research.

Later, Vincent and Josephine accompanied their parents for a family fun day in the city of Qeqertarsuaq, with the teenagers participating in a football match and the family mile race for all residents.

The young royals share their parents' love of sport and have taken part in their father's Royal Run event in Denmark in recent years.

Frederik and Mary are also huge tennis fans, and in 2020, they shared footage of their children practising their serves on the court.

Stepping into the public eye

Since their father became king in January following Queen Margrethe's abdication, Vincent and Josephine have made more public appearances.

As well as joining their parents and elder siblings, Crown Prince Christian and Princess Isabella, on the palace balcony at the proclamation, Vincent and Josephine also stepped out for Frederik's 56th birthday celebrations at Frederik VIII's Palace, Amalienborg in May.

Ahead of the Euro 2024 tournament, Frederik posed for a snap with the twins in matching Danish football kits, with Josephine joining her father at the England vs Denmark match in Germany, where they chatted with the Prince of Wales.

Last week, Frederik and Mary marked a new milestone as Crown Prince Christian, 18, graduated from high school with his younger siblings also in attendance to celebrate.

While Princess Isabella, 17, is about to go into her final year at Øregård Gymnasium in Hellerup, Prince Vincent attends Tranegårdskolen, while Princess Josephine started 6th grade at Kildegård Private School in August 2023. The palace did not share the reason behind Josephine's school move.
