According to the Mail on Sunday, the future Queen of England managed to enter the Hollywood Arms pub and restaurant in the posh London suburb of Chelsea, through a secret back entrance that was first installed for Prince Harry.
The publication also reports that the Duke of Sussex (and now the Duchess of Cambridge) will use the secret entrance so as to acquire a drink in their local pub without causing a stir.
Kate was there to send off her daughter - Princess Charlotte - for her first day in school back in September, and a source told PEOPLE that the Duchess is a very hands-on mum when it comes to all her children.
"She wants to emulate her upbringing, living in the countryside with a close-knit family," a friend of the royal told PEOPLE.
"She desperately wants that normality for her own kids."
