Prince Louis 'warned' by Mike Tindall to behave at Platinum Pageant in hilarious royal box moment

• Mike Tindall appears to have 'warned' Prince Louis to behave himself at the Platinum Pageant after the four-year-old's hilarious antics at the Trooping the Colour. 
• Prince William and Kate Middleton's youngest child earned a reputation as the Cambridge family's most expressive, and arguably most lovable, member with his cheeky facial expressions at the Queen's birthday parade on Friday.

Prince Louis was given a warning from Mike Tindall to behave at the Platinum Jubilee Pageant today - but it looks like it was issued in good jest. 

The adorable four-year-old joined his parents, Prince William and Kate Middleton, and his two older siblings, Prince George, 8, and Princess Charlotte, 7, for a special parade at Buckingham Palace on Sunday in honor of the Queen's Platinum Jubilee. 

The exciting street performance, which will trace the incredible story of Her Majesty's 70-year-long reign, marks the final event in an intensive four-day bank holiday weekend of patriotic celebrations. It will also likely be the last public sighting of the Cambridge children for a while, with their upcoming summer holidays expected to whisk them away to the family's Norfolk home of Amner Hall. 

Prince William and Kate Middleton's three kids have been notably visible throughout the weekend's festivities, accompanying their royal parents to many of the Jubilee's highlights and even getting involved in the duties themselves. 

From Princess Charlotte sharing the Queen's musical talents in Cardiff to Prince Louis' sweet moment with the Queen on the balcony at the Trooping the Color, there's been no shortage of Cambridge cuteness over the past few days. 

There's also been plenty of funny moments courtesy of the royal infants, who are likely unaware of the level of scrutiny their family is under right now. Prince Louis has undoubtedly won the prize for the most entertaining Cambridge tot at the Jubilee, treating the public to a series of hilarious faces at the Trooping the Color on Friday that has now gone viral. 

It looks like Louis' royal relatives have also taken notice of his cheeky antics - and they'll even call him out on it, if needs be. At the beginning of today's Platinum Pageant, Mike Tindall was photographed jokingly giving the preschooler the 'eyes', as a friendly reminder that he'll be watching his behavior in the royal box during the show. 

Kate Middleton, who was sitting next to Louis during the exchange, appeared amused by the banter between her cousin-in-law and youngest son. The Duchess was also noticeably engaged with Louis throughout the performance, regularly leaning in to chat to him and pointing out various attractions as the event unfolded.
