Whether or not they are born into royalty, young children will always be prone to tantrums, cheekiness and moments of naughtiness.
And these little Princes and Princesses are certainly no exception! Prince William and Prince Harry had plenty of cheeky moments during their childhoods, and the current generation of young royals are the same.
From sticking their tongues out during royal engagements, pinching unsuspecting teachers, or just playing up for mum and dad, take a look through our gallery to see the most mischievous moments from these royal rascals...

Prince Louis stole the show when he joined his parents in the royal box at the Jubilee pageant during the Queen's Platinum Jubilee in June 2022.

He was photographed making a series of unforgettable cheeky faces – including sticking his tongue out at mum, the Princess of Wales, and pretending to be a lion.

Savannah nearly broke the internet in June 2018 after she was pictured telling Prince George to be quiet during the Trooping the Colour ceremony. She wasn't afraid to tell her little cousin what to do, and he didn't seem to mind either!
At one point, she was pictured putting her hand over Prince George's mouth to quiet him down... after her attempts at shushing him didn't work the first time! (All while dad Prince William kept a close eye on them, of course!)

Her dad, Mike, previously spoke on Good Morning Britain aboutthe moment Mia held up her great-grandmother's handbag for her 90th birthday portrait, saying: "It just happened at the right time. She was being a bit naughty. The Queen got it quite right when she told her, 'Just hold the handbag now,' and she did that. It ended up being a great photo for her."
