Prince Harry and Meghan Markle’s official wedding photographer has revealed he had just three minutes to shoot the “exhausted” couple.

Alexi Lubomirski, who also took the pair’s stunning official engagement photos, said the shot of Meghan entwined in Harry’s legs happened when the tired bride “slumped” on the groom.

The pictures have been called the most intimate royal wedding images ever seen.

Lubomirski told the BBC the shoot was “one of those magical moments”.

He said: “We went out there and had about three-and-a-half minutes to take some quick shots because everything was running like clockwork.

“It was just one of those magical moments when you’re a photographer and everything falls into place. I said ‘just before you go in, sit on those stairs.’

“And she just slumped between his legs and there was this moment where they were just laughing because they were exhausted and thinking finally it’s all over. It was one of these beautiful moments.”

Days after their dream ceremony, the couple got back to work, attending their first official event as a married couple.

Meghan looked particularly regal at the garden party held at Buckingham Palace donning a $590 peach dress from British brand Goat, a custom hat by Philip Treacy and nude pumps.

Goat is a brand often worn by the Catherine, the Duchess of Cambridge, Meghan’s new sister-in-law.

More than 6,000 charity workers were invited for the party, to celebrate Prince Charles’s 70th birthday, where they were treated to a speech from Harry, musical performances and a customary cup of tea.

The event was held ahead of Prince Charles’ actual birthday which is in November.

Meghan and Harry had delayed their honeymoon so they could attend the event.

The pair looked like they were enjoying their first week as husband and wife, with Meghan touching Harry’s back as they walked up the stairs of Buckingham Palace.

Hundreds of royal fans had lined the streets surrounding the palace in an attempt to get glimpse of the newlyweds.

Prince Harry was wearing a traditional morning suit with a yellow waistcoat and blue tie.

He gave a speech where he paid tribute to his father’s charity work.

“His enthusiasm and energy are truly infectious; it has certainly inspired William and I to get involved in issues we care passionately about and to do whatever we can to make a difference. In fact, many of the issues William and I now work on are subjects we were introduced to by our father growing up,” Harry said.

“So, Pa, while I know that you’ve asked that today not be about you, you must forgive me if I don’t listen to you — much like when I was younger — and instead, I ask everyone here to say a huge thank you to you, for your incredible work over nearly 50 years.”

The Prince, who was forced to bat off a rogue bee during the address, also asked the audience to take a minute to remember the one year anniversary of the Manchester terrorist attack.

He said his brother William would have been at their father’s party were he not attending a tribute service in Manchester.
