Piers Morgan couldn't resist a dig at Meghan Markle as the Queen began her Platinum Jubilee celebrations.
The former GMB host, 57, shared a montage of pictures of Prince William and Kate's youngest son Louis as he made faces while standing next to the monarch.
Louis was photographed pulling faces and putting his hands over her eyes and ears while he attended the show.
Piers tweeted: "Is this when Aunty Meghan arrived?"
His followers weren't too impressed, with one tweeting: "Five years later and you're still obsessed."
While another commented: "You’ve been saying all week about this being the Queens weekend and to not make it all about Meghan which you were correct to say and I know this is meant in a humorous manner but you aren’t helping the cause here."
A third wrote: "Louis is definitely going to be the fun one of his family."
It came as thousands of people lined the streets for the celebrations - cheering as an RAF Red Arrows flypast zoomed across London.
Meghan Markle appeared in a playful mood as she joined members of the Royal Family at for the Trooping the Colour parade - before the monarch wowed the huge crowds at Buckingham Palace.
Prince Andrew, it was later confirmed, sat the event out after testing positive for Covid.
Meghan, who arrived in the UK last night with Prince Harry, was seen joking with the younger royals during the event.
Kate, George and Charlotte waved from their royal carriage and Prince Louis stole the show on the palace balcony, kicking off celebrations for the Queen's Platinum Jubilee.
Prince Charles and Prince William led the parade as thousands lined the streets to mark the start of the four-day bank holiday.
