On Tuesday, it was announced that Prince Harry has taken on a job at the Silicon Valley coaching and mental health firm <a href="https://www.thenationalnews.com/lifestyle/wellbeing/prince-harry-to-take-up-role-at-mental-health-company-betterup-1.1189983">BetterUp Inc</a>. The Duke of Sussex stepped down as a senior royal in 2020, and is set to become the chief impact officer at the company, a role that he hopes "creates impact in people's lives". However, Harry is not the first, and certainly won't be the last, international royal to take a regular day job. Here, we round up the royals that have been put to work ... Prince Nikolai of Denmark, 21, is the grandson of Queen Margrethe II of Denmark and eldest son of Prince Joachim, the queen's second son. Prince Joachim's elder brother, Prince Frederik is the country's crown prince. Prince Nikolai is currently seventh in line to the Danish throne and works as a full-time model. He has appeared on Dior and Burberry runways, and walked during London Fashion Week in 2018. Of his son, Prince Joachim, who has worked as a farmer in the past, said: "He shouldn't be forced into anything. Nikolai's life must go completely according to his own plan. I want to help him along the way and try to inspire him." Princess Martha Louise, 49, is the only daughter of Norway's King Harald V and Queen Sonja. She is the eldest child, however, her younger brother Haakon, Crown Prince of Norway, is first in line for the throne. Although she is third in line, she is not a member of the royal house and rarely makes official public engagements. She trained as a physiotherapist, but has never practiced. Instead, she established an entertainment business that creates public and televised performances from traditional Norwegian folk tales. She has also released her own children's book. Granddaughter of Queen Elizabeth II, Britain's Princess Beatrice, 32, has had a number of jobs, including volunteering as a sales assistant at London department store Selfridges in the summer of 2008.

She is also "in charge of [a company] programme to engage senior business chiefs around the world to support women in leadership". Like her sister Princess Beatrice, Princess Eugenie, 31, has taken on a number of jobs away from her royal duties. After graduating from university, she moved to New York City to work for auction firm Paddle8 as a benefit auctions manager in 2013.

The 34-year-old is the niece of Prince Albert, and is 11th in the line of succession to Monaco's throne. Rainier III, Prince of Monaco, and American actress Grace Kelly were her maternal grandparents. Before her role at Chanel, Casiraghi modelled for top brands including Gucci and Yves Saint Laurent. Zara Tindall, 39, is the granddaughter of Queen Elizabeth II and daughter of Britain's <a href="https://www.thenationalnews.com/lifestyle/home/princess-anne-offers-a-look-inside-her-refreshingly-normal-home-with-new-photo-1.1162061">Anne, Princess Royal</a>.

In the London 2012 Summer Olympics, Tindall represented Team GB and won a silver medal. She did not qualify for the Rio 2016 Summer Olympics. She is married to rugby player Mike Tindall and the couple have three children, Mia Grace, 7, and Lena Elizabeth, 2, and<a href="https://www.thenationalnews.com/lifestyle/family/all-the-celebrities-who-had-babies-in-2021-zara-and-mike-tindall-welcome-baby-boy-queen-elizabeth-ii-s-10th-great-grandchild-1.1167991"> Lucas Philip</a>, who was born this week.

SEL's London headquarters are located on Buckingham Palace Road, making his royal connection clear. Interestingly, Phillips uses his royal status to make money. In January 2020, he featured in a Chinese commercial for Bright Food, advertising milk. In the video, he was described as a "British royal family member". The Greek monarchy was abolished in 1973, however, Princess Marie-Chantal is a princess of Denmark by marriage. Her husband is Pavlos, Crown Prince of Greece, a male-line descendant of Christian IX of Denmark. Princess Marie-Chantal, 52, works in the fashion world.

He is the younger brother of Pavlos, Crown Prince of Greece and Princess Marie-Chantal's husband, and is named after Britain's Prince Philip, Duke of Edinburgh, who was born Prince Philip of Greece and Denmark. He is also the godson of the late Princess Diana. Prince Philippos, 34, works in finance and has worked in New York City at Ortelius Capital Partners, "an alternative investment group specialising in hedge funds and private equity", since 2014. His LinkedIn currently lists him as an analyst at the company. In 2020, he married Nina Flohr, daughter of Swiss billionaire Thomas Flohr. The most senior royal on our list is King Willem-Alexander, king of the Netherlands. He acceded to the throne following his mother's abdication in 2013. His mother is Beatrix of the Netherlands. In 2017, it was revealed that avid pilot King Willem-Alexander had served as a first officer on KLM flights for 21 years, "even after his accession to the throne". It is said he was "rarely recognised" while in KLM uniform.
