Prince Louis displayed decidedly unroyal behavior while watching the Platinum Jubilee pageant on Sunday.
The 4-year-old was caught putting his hand over his mother Kate Middleton’s mouth in a video that has gone viral on social media.
When the Duchess of Cambridge, 40, politely tried to stop him – no doubt gritting his teeth – the rambunctious boy made a series of faces, stuck his tongue out and put his thumb to his nose while wiggling his remaining fingers.
Louis also decided to stand up in his chair and appeared to throw a cushion – that’s when Kate made the wise decision to take a spell break with her youngest.
Louis’ behavior even caught the attention of Mike Tindall, who is married to Prince William’s cousin, Zara Tindall.
The retired rugby player was caught jokingly telling Louis that he was watching him (and no doubt expected him to be a good little boy).
The adorable young man also took the time to give his mother a big kiss and spent some of it sitting on the lap of his grandfather, Prince Charles.
It certainly wasn’t the first time Louis showed his exuberant spirit in public.
At Thursday’s Trooping the Color ceremony, he and his siblings Prince George and Princess Charlotte watched the motorcade through the palace windows. Louis stole the show with a fiery salute.
He then burst onto the balcony as the royal family gathered to greet, stepping past his 96-year-old great-grandmother for a privileged viewing position. Louis was photographed pulling a host of animated faces, including an overreaction to loud planes flying overhead, which involved screaming, hands over ears and eyes closed.
Lipreaders also analyzed that he succinctly told Charlotte to “move around” on the balcony.
Louis ended up joining his parents, siblings, Prince Charles, Camilla Parker-Bowles and the Queen on the balcony of Buckingham Palace at the end of the Platinum Jubilee pageant – but this time mum was taking no chances . The Duchess stood directly behind her son, who bears a strong resemblance to his father, Michael Middleton, and held him back when he came forward.
Page Six looks forward to many more cheeky moments from this royal scene-stealer.
