A secret tunnel helps royals get from St James's Palace to a cocktail bar, it has been claimed.
Princess Eugenie's husband reportedly confessed to the underground path which goes to Duke's Bar.
Such a tunnel may seem unlikely but nearby Duke's is on the same estate as the palace, which was built in the 16th century and is still in active use by the royals.
Jack Brooksbank is said to have let slip the revelation to the Daily Mail, speaking about it at a party in London which was sponsored by his tequila brand, Casamigos.
He said: "There is one to Dukes Bar from St James’s Palace. I haven’t used it yet, but I’d love to check it out."
The bar is in the five-star Dukes Hotel and serves a £17 martini.
The royals are no stranger to tunnel rumours with there being frequent gossip about a secret underground network linking Buckingham Palace to various other parts of London, such as Whitehall or maybe the Houses of Parliament.
Other unproven rumours include a tunnel between the palace and Clarence House, and a branch of the Post Office Railway running right under the Palace.
The Queen does have a secret escape out of her residence at Windsor Castle.
Back in the 1000s, secret passageways and escape routes were a necessity, and one was included by the architects of the royal residence, which leads out onto the street.
Presenter Fiona Bruce revealed the hidden passageway for the first time on camera, saying you can still find evidence of the castle’s “war like origins” if “you know where to look”.
Footage from a 2011 documentary shows Fiona standing in a small, ordinary-looking room.
She says: “This is an office just tucked away in a corner of Windsor Castle. But look under here.”
The unassuming room holds a big secret, as Fiona lifts up the carpet to reveal a wooden trapdoor.
She said: “As if by magic, just lift these and the medieval castle emerges."
