'I'm a royal expert and Prince Harry will be furious with Meghan Markle's latest move'

Prince Harry will likely be "extremely annoyed" about Meghan Markle's decision to use their children to promote her Netflix show. Taking to Instagram on Monday, the 44-year-old shared a series of behind-the-scenes pictures from the set of With Love, Meghan.

Included in the eight newly-released pictures, Prince Archie, six, and four-year-old Princess Lilibet were included in three of them. In one picture, the sibling duo can be seen watching a screen on the set. Lilibet showed off her red locks as she can be seen holding a piece of equipment up to her ear. Next to his little sister, Archie is seen holding some sound equipment as he watches the screen on the table.

In a separate snap, Lilibet can be seen facing away from the camera as she sits on a chair behind the scenes of the set.

Also in the picture appears to be Meghan's late beloved dog Guy, who featured in the series - as well as her friend Daniel Martin posing from behind the door.

Meghan also posted a picture of six-year-old Archie on the screen holding a director's clapboard, with his face carefully covered by a grey-heart emoji.

As reported by The Sun, royal expert Hugo Vickers said: "[Harry] ought to be extremely annoyed. Obviously, I don't know what he thinks, but I think he does what he's told probably."

The couple are both known to want to keep their two children out of the spotlight, especially with the family now living in California and away from the constraints of the Royal Family.

Despite this, Meghan has frequency started to release pictues of Lilibet - whom they affectionately refer to as 'Lili' - and Archie.

Spaking on an episode of "A Right Royal Podcast" earlier this year, The Sun's royal editor Matt Wilkinson said: "My understanding of this is that up to a certain stage Harry would much rather his children were not seen."
