The Duke and Duchess of Sussex finally created their own Instagram account on Tuesday.

The account, which has the username @sussexroyal, gained 2.1 million followers less than 24 hours after they published their first post.

One photo stood out from the rest, as this image has never been seen before by the public.

The photo, which shows Prince Harry and Markle waving to fans from the balcony of the Grand Pacific Hotel during their royal tour of Fiji in October, was taken from behind, and it makes the photo flashes look magical.

A spokesperson for the couple at Kensington Palace confirmed to INSIDER that the photo has never been officially released.

The photos of the couple on the balcony that were initially released to the public were all taken from below the balcony, like this one.

Although it's unclear if we will be getting any more behind-the-scenes shots of the couple, Harry and Markle did say the account would be used to share "important announcements" - so perhaps we can expect some royal baby updates as Markle is due to give birth this month.

Their first post reads: "'Welcome to our official Instagram; we look forward to sharing the work that drives us, the causes we support, important announcements, and the opportunity to shine a light on key issues.

"We thank you for your support, and welcome you to @sussexroyal.' -Harry & Meghan."

The couple's new social media presence should come to no surprise to those who follow the pair closely.

Harry and Markle, who previously shared a joint Twitter and Instagram account with the Duke and Duchess of Cambridge, recently revealed they would be splitting households from the couple in the spring.
