Celebrations were in order for the Danish royal family on Monday as Crown Prince Frederik and Crown Princess Mary's youngest children turned 13.
The Danish royal palace shared a new photograph of Frederik and Mary's twins, Prince Vincent and Princess Josephine, to mark the occasion.
The image, which appears to have been taken at the family's home at Amalienborg Palace in Copenhagen, shows the youngsters wearing smart outfits.
Vincent sported a navy suit with a blue patterned tie, while his twin Josephine matched in a blazer and a powder blue blouse with flared cuffs.
The teenage royals have two older siblings – Prince Christian, 18, and Princess Isabella, 16.
Vincent and Josephine's milestone birthday comes just days before their father Frederik will become King of Denmark.

Prince Vincent and Princess Josephine – all you need to know

The twins were christened in April 2011 at the chapel of Church of Holmen. Josephine wore a christening gown found among her late great-grandmother Queen Ingrid's belongings, making her the first child of a future Danish monarch not to wear the family's traditional christening gown – which was worn by her twin brother.

However, last summer it was confirmed by the palace that Josephine had moved to Kildegård Privatskole in Hellerup. The palace did not share a reason for the change in the princess' schooling.
