And they apparently still use it.
The royal family are more talked about than Hollywood movie stars, breaking the internet by simply leaving the house.
It’s hardly surprising therefore that they need to take extreme precautions to keep their private lives private.
Code names are pretty common among the Mountbatten-Windsors, with Prince William going by the pseudonym ‘Steve’ at university, and Prince Harry choosing the alter ego ‘Spike’ for his social media accounts, allowing them to fly under the radar and to ensure no gossip got out when their pals talked about them in public.
It even emerged this week that the Queen had an unexpected codename, with her security reportedly referring to the monarch as ‘Sharon’ in public. Yes, really.
This week however it was a different security measure that made news as it emerged that Prince Harry and Kate Middleton have a secret door to their favourite pub.
The Hollywood Arms in Chelsea is known to be Prince Harry’s favourite watering hole, but he is rarely seen entering the pub because he reportedly has his own secret entrance.
Yes, really. According to the Daily Mail, the Duke of Sussex had a secret back door entrance to the pub installed back in his ‘party days’ so that he could enter incognito.
And he’s not the only royal to make the most of the secret passageway, via an alley behind the pub, with sister-in-law Kate Middleton also known to use it.
Royals – they’re just like us!
