Princess Athena celebrates her 8th birthday on Friday, 24 January 2020, with her family in Paris.
Prince Joachim, Princess Marie and their two children moved to France last year whilst he completes military training at the Ecole Militaire.
Prince Henrik and Princess Athena are currently attending a new school whilst in France.
Danish magazine, Billed-Bladet, has said Princess Athena will probably have a ‘nice party’ with her family at home, rather than one with her new classmates.
Grandmother Queen Margrethe is said to be sending ‘a sweet birthday greeting’.
The Danish Royal Court has released new photos, taken by her mother Princess Marie, to mark the occasion.
Her Highness Athena Marguerite Françoise Marie, the youngest child and only daughter of Prince Joachim and his second wife Princess Marie, was born at 8.27 am on 24 January 2012 at Rigshospitalet (Copenhagen University Hospital) in Copenhagen.
The little princess was 49 cm (about 19 inches) in length and weighed in at 2.930 kg (about 6 pounds 7 ounces).
Her Highness Princess Athena is currently tenth in the line of succession to the Danish throne.
She has two older brothers, Nikolai and Felix from her father’s first marriage, and an older brother Henrik.
Princess Athena joined her older brother when she started Grade 1 at St Joseph Sisteren’s School in Ordrup on Friday in August 2017, which is close to her home in Klampenborg, a northern suburb of Copenhagen.
