Prince Harry couldn't help but grin as the Queen inspected soldiers at their passing-out Sovereign's Parade at Sandhurt Military Academy. The wonderful moment between grandmother and grandson was caught on camera as Her Majesty smiled at Prince Harry while he stared ahead and tried to remain composed, though he was clearly unable to keep a straight face.
"Now this is a face I recognise," the Queen famously said.
The Prince has a great relationship with his grandmother, and recently treated her to a special birthday gift to celebrate her 90th. During the dinner held in the Queen's honour, ventriloquist Nina Conti performed and had Harry act as her dummy.
A source told HELLO!: "It was genuinely brilliant. He must have been practising it because he had to do the actions in time with her speaking. It was intensely funny because he was so good."
Prince Harry had crowds laughing as he pulled a silly face after seeing a sign which read: "red heads rule," jokily referring to Harry's hair.
The Prince greeted members of the public outside the Australian War Memorial during an official visit prior to the end of his military career in 2015.
The royal melted hearts across the nation when he visited the charity Canine Partners Training Centre and was unable to resist picking up an adorable eight-week-old puppy.
Prince Harry proved himself to be quite the passionate Star Wars fan when he visited the set with his older brother William. The pair met the film's stars Daisy Ridley and John Boyega, marvelled over the new robot companion BB-8 and play fought with lightsabers.
Grumbling over being given the red lightsaber, which is used by villains in the movies, Harry said: "Why do I always have to be the baddy?" then said: "Come on, let's dance."
While visiting a school for Sky Sports TV show Game Changers, Harry joined in on the fun when children had to throw balls at targets with Harry's face printed on them.
Co-presenter Darren Campbell commented on how well Harry had done at the school, saying: "When you are doing a kids' TV show, the children know when somebody's fake and not there for the right reasons. They know Prince Harry was there for the right reasons. It will be a day those young people won't forget."
Harry was snapped showing children photographs of his trip as he visited a herd boy night school. The school was constructed by Sentebale, the Prince's charity that provides healthcare and education to children in Lesotho.
Proud of his photography skills, Harry said: "I have always enjoyed photography and the challenges that come with trying to capture the perfect shot, although privately I don't take many photos.
"The best photos I have are in my head - I have some very special memories, mostly from Africa. But on this visit, I had the time and opportunity to be on the other side of the camera and take some photos in the stunning country of Lesotho for my charity Sentebale."
While playing five-a-side football on opposing teams during a visit to the Coach Core project at Gorbals Leisure Centre in Glasgow, Scotland, the two brothers William and Harry showed their competitive streaks as they attempted to block each other.
The royal has always been passionate about working with sports charities, and posed with Eliud Kipchoge and Jemima Sumgong after they won the men and women races while supporting the Virgin London Marathon 2016.
The Prince has been busy filming for Sky Sports Gamechangers, and went to visit a school where one student asked if he was ever going to be King. He cheerfully replied: "That's the question everybody wanted, let's be honest! You'll be glad to know, probably not! Oh look at the disappointment! I love that! I'm going to give you a high-five."
Harry enjoyed his visit to Nepal so much that he extended his stay to help Team Rubicon rebuild a village in Lapubesi after last year's earthquake. The Prince showed his work ethic by clearing wood for a solar farm site.
Prince Harry could have played 007 himself as he joined his brother and sister-in-law on the red carpet for the Royal Film Performance of the James Bond action thriller, Spectre.
Dressed in a black tuxedo while showing a little stubble, the Prince stole the show as he greeted the crowd at the Royal Albert Hall.
