The Queen was once almost shot by one of her own guards while she took a late-night stroll through palace grounds, it has been reported.
The guard is said to have shouted into the darkness when he spotted a figure walking around Buckingham Palace at 3am, believing it might be an intruder.
But the shadowy suspect was in fact Her Majesty, who had stepped out for some fresh air because she couldn't sleep, The Times reported.
The guard confessed to Her Majesty he had nearly fired his weapon, to which she quipped: "Next time I'll ring through beforehand so you don't have to shoot me."
