Supernanny star Jo Frost has revealed what she thought of how Kate Middleton dealt with cheeky Prince Louis during the Queen's Platinum Jubilee celebrations.
Four-year-old Prince Louis entertained the nation throughout the weekend with his hilarious reactions during events such as the RAF flypast and Sunday pageant.
At one point, the youngster covered his mother's mouth as she attempted to speak to him, shook his finger at her and blew her a raspberry.
Kate, 40, was seen keeping a close eye on her youngest son throughout the weekend's celebrations - but that didn't stop the cheeky four-year-old from pulling a series of expressions.
At one point the prince was spotted thumbing his nose and wandering over to sit on Prince Charles's lap during the pageant show after growing restless.

He previously had a cheeky encounter with Mike Tindall who could be seen jokily warning the four-year-old to behave. The young Prince, four, was also spotted enthusiastically dancing, before pausing to eat a chocolate biscuit.
While Prince Louis' actions stole the hearts of the nation, they also caught the attention of Supernanny star Jo Frost.
The parenting guru commented on a video of the prince misbehaving, which was shared on Hello! Magazine's Instagram page.
Jo praised Kate, saying: "Love how mum is addressing in public prince Louis needing to listen up and do as his [sic] told."
She added: "Unlike other children the royals are expected by the world to behave a certain way but at the end of the day they are children, royalty or not.
"The whole fanfare will become a little too much when you're young - it was a long day, little moments like this are going to happen, especially if you are strong willed, sensitive and actually I would go as far as to say a highly sensitive child in my professional opinion."
In another post, the Supernanny star said: "The Duke and Duchess of Cambridge are a great example, Catherine has never been afraid to tell the kids to stop in public, I love that about her.
Hundreds of people commented on the Instagram post, with many praising the young boy and the Duke and Duchess of Cambridge.
One said: "This is hysterical and Kate handles it perfectly!!!!! It’s been a long and busy four days of celebrations…hats off to W&K doing so incredibly well & also with three kids!!"
As well as during the pageant, Prince Louis also stole the show during Trooping The Colour after he was wowed by the Red Arrows.
He was photographed chatting to his great-grandmother The Queen as they watched on from the balcony of Buckingham Palace.
On social media, one royal fan wrote: "Oh my Gosh!!!! I can't!! Cuteness overload!! Prince Louis is so freaking adorable!"
Another wrote: "Prince Louis is stealing the show once again."
A third added: "This child is a joy to watch (probably a handful to parent!) but what a super little character he appears to be!"
