While the royal family may be on their best behaviour 99 per cent of the time, the likes of Prince William, Prince Harry and the Queen can't resist showing their playful side sometimes! Prince George has delighted fans by pulling faces on multiple occasions and Prince Louis captured everyone's hearts at the Platinum Jubilee. If you're looking for a spot of entertainment, we've rounded up some photos of when the royal family have let their prim and proper facade slip…

Prince Louis
As if the Jubilee Pageant for the Queen wasn't entertaining enough, we also had some giggles at the many faces of four-year-old Prince Louis during the show. At one point he was even caught on camera sticking his tongue out at his mum! Luckily the Duchess wasn't phased by the cheeky behaviour an d simply tried to keep her son occupied by pointing out the floats going by along The Mall.
Princess Charlotte
In August 2019, Prince William and Kate's daughter Princess Charlotte had the crowds in hysterics after she cheekily stuck her tongue out at the King's Cup regatta in Cowes, Isle of Wight. Just before heading to the prize-giving ceremony, the Duchess bent down to encourage her children to wave to the public. Charlotte had other ideas though, as she leant forward and hilariously poked her tongue out!

Prince George
The young royal is quite a fan of poking his tongue out, whatever the occasion – here he is striking his best pose in Canada.
Kate Middleton
It's hard to tell whether the Duchess was simply licking her lips or giving a cheeky tongue poke when she was pictured greeting children at Gardens by the Bay during her visit to Singapore in 2012. We like to think it's the latter!

Prince Harry
Just like his nephew Prince George, it was one of his favourite faces to pull as a child! Here he is as a four-year-old perfecting the look, much to the surprise of his mother, Princess Diana.
Prince Louis
The youngest of the Cambridge kids, Prince Louis, had his mum Kate and his aunt Meghan in giggles as he stuck his tongue out during a family day at the polo in July 2019. Louis adorably wore his mum's sunglasses for his hilarious little sketch.
Princess Charlotte
Stealing the limelight at Prince Harry and Meghan's wedding back in May 2018 was Princess Charlotte as she arrived at St George's Chapel.
Prince George
Looking less cheeky and more like he was deep in thought, George had his tongue on display as he accompanied his dad to the St Mary's Hospital to visit his newborn baby brother Prince Louis back in 2018.

Prince William
Long before he was a father-of-three, Prince William proved he's a big kid at heart with this mischievous look.

The Queen
Even the Queen can't resist her silly side sometimes!
Mia Tindall
It appears little Mia has the same concentration face as her mother Zara when getting up to mischief. Back in 2017, she seemed to be having plenty of fun playing around the coffee sign at the Whatley Manor Horse Trials at Gatcombe Park.
Prince George
In 2015, Prince George was making everyone laugh as he was held up by nanny Maria to watch the proceedings outside of Buckingham Palace during Trooping the Colour. The adorable youngster stuck out his tongue and clapped while watching the action below!
Prince Harry
Prince Harry catches his breath after a boxing training session, and it's not the first time he's pulled such a face.
Prince Philip
Always the joker, look at Prince Philip in 2012 being a cheeky grandfather.
Prince Charles
Looks like someone was hungry! Prince Charles took a tour of the newly refurbished Fortnum and Mason in 2007 and was clearly waiting for some snacks…
