Well, according to Joey Essex, the Duke of Edinburgh knew who Joey was during a recent royal walkabout in Windsor, even inviting the Essex star to approach him.
Joey told The Mirror he'd been filming scenes for his new ITV2 show on The Queen's 90th birthday when he came face-fo-face with Prince Philip.
The only problem? Joey didn't know who he was.
Joey told the newspaper: "I didn't know who he was. He recognised me. He said, 'Jump over the gate.' If I'd known it was Prince Philip I would have done it."
Apparently Buckingham Palace declined to comment on the incident so we'll never know if Prince Philip is a secret TOWIE fan or not…
Joey has been working on a new episode in his Educating Joey Essex series, all about the monarch's milestone birthday. He was spotted filming at Windsor Castle in April, where he bumped into Gogglebox favourites Sandra and Sandy!
Former BBC royal correspondent Jennie Bond has also been involved with the project, telling Bang Showbiz: "We were filming all day around Buckingham Palace, Clarence House and the Tower of London. I'll be educating Joey about royalty, so that's been fun.
"His knowledge was shaky, shaky would sum it up - but he's a big admirer of the Queen ... (he has a) shaky knowledge of who is who and who does what and there were a number of things that had me in fits of giggles."
