Princess Charlotte and Prince George look adorable in unseen photo

The unseen group shot is far less formal than many of the official wedding photographs captured by royal photographer Alexi Lubomirski.

Princess Charlotte, who had just celebrated her third birthday at the time of the royal wedding, walked down the aisle alongside Meghan at St George's Chapel, looking like a mini princess in her flowing frock and pretty flower garland.

Meanwhile, Prince George, who was nearly five, fitted the part perfectly in a military-style outfit. Reflecting on his fairytale wedding at St George's Chapel in Windsor, Prince Harry narrates in the episode: "She [Meghan] sacrificed everything that she ever knew, the freedom that she had, to join me in my world.

"And then, pretty soon after that, I ended up sacrificing everything that I knew to join her in her world."

Princess Charlotte was three-years-old at Harry & Meghan's royal wedding

Several moments from Meghan and Harry's royal wedding on 19 May 2018 will stay with us forever, from the Duchess' trailblazing choice to walk herself down the aisle, to the couple's first kiss as man and wife.

But very little is known about their wedding reception at Frogmore Hall in Windsor, and next to no photos have ever been released from inside the celebrations, until now.

In the first trailer for their explosive new Netflix show the couple release several candid photos, including one of them partying with the likes of Zara and Mike Tindall on their big day.
