The young actor made her first professional role as Kate Middleton on Netflix’s hit series The Crown.
Meg Bellamy, 19, former principal of St Crispins School in Wokingham, Berkshire, was selected after submitting a selfie audition after casting calls were put out on social media.
Also making their screen debuts are Ed McVey, 21, and Rufus Kampa, 16, playing younger versions of the Duchess of Cambridge’s current husband, Prince William.
All three will appear in the show’s sixth and final series, which begins filming later this year.
The Crown is a historical drama chronicling the reign of Queen Elizabeth II, and its sixth series will take place in the years following the death of Princess Diana, Princess of Wales in 1997.
Kampa will play Prince William shortly after his mother’s death, while McVeigh and Bellamy will reportedly play the Duchess when they were students at the University of St. Andrews when they met in 2001.
According to the Daily Telegraph, Bellamy is believed to have landed the role just months after leaving St Crispins, a general hospital, and has no professional acting experience.
She was reportedly awarded an A* in drama A level, appeared in many school productions, and was also said to have worked as a performer at Legoland in nearby Windsor.
McVey graduated from Drama Center London in 2021 and worked as an understudy in the Old Vic’s play Camp Siegfried, but has yet to appear on screen.
Kampa has appeared in numerous stage productions, most recently as the title character in the musical version of Adrian Moll’s Secret Diary, aged 13 and 3/4, and as Oliver’s skilful Dodger.
Other stars who have appeared in The Crown include Olivia Colman, who played the Queen. Matt Smith as Prince Philip. Helena Bonham Carter as Princess Margaret.
The fifth series, set to air in November, will include an all-new cast, with Imelda Staunton as the Queen, Jonathan Pryce as Prince Phillip, and Lesley Manville as Princess Margaret.
The series also stars Dominic West as Prince Charles and Elizabeth Debicki as Diana, Princess of Wales.
Asked about last year’s show, Prince Harry described it as “fiction” but “loosely based on truth.”
“It gives you a rough idea of that lifestyle, the pressure to prioritize duty and service over family and everything else, and what comes out of that,” he said.
