The tennis star was summoned by Royal Appointment as one of the celebrities chosen to send Her Majesty a special Jubilee message for Saturday’s Platinum party.
And Raducanu was careful to talk properly in the video when she joined Sir David Attenborough, David Beckham, Stephen Fry and Dame Julie Andrews in saluting the Queen’s 70 years on the throne.
She revealed: “The message for the Queen, when I was asked to do that I was definitely a bit nervous.
“I was pronouncing all my Ts. It was pretty surreal and a real honour of course. And to see my face on the screen, I was like: ‘This can’t be real!’”
The invite was recognition for her incredible US Open triumph last September.
Raducanu described the past 12 months as ‘surreal’.
A first-round defeat to Brit Harriet Dart at the Nottingham Open in June 2021 was her first appearance on the WTA circuit.
That was just a few weeks after taking her A Levels.
Few could have predicted the meteoric rise since, first reaching the Wimbledon fourth round and then the transatlantic triumph.
