A cheeky Prince George was snapped sticking his tongue out on his way to Windsor after the Queen's funeral.
Amateur photographer Matt White, 30, snapped a photo of the nine-year-old pulling a funny face, out of view of his mother Kate Middleton on Monday.
Prince George became second-in-line to the throne after the death of Queen Elizabeth II.
George, the future King, and his younger sister Charlotte, seven, bravely walked behind their parents, the Prince and Princess of Wales, as her Majesty's coffin was carried through Westminster Abbey.
The Prince's candid moment comes after his younger brother Prince Louis was snapped holding his hands over his ears and screaming on the Buckingham Palace balcony during the Queen's Platinum Jubilee celebrations earlier this year.
Prince Louis, who is just four-years-old, did not attend the Queen's funeral, given his tender age.
Matt, from Greenhithe, Kent, stayed out all night between Sunday and Monday to get a front row seat on the Queen's funeral parade.
The sales consultant said he didn't sleep a wink throughout the night, but that the wait was well worth it.
He said: "The atmosphere through the whole night was just amazing. It was such a great crowd and we were on the barrier so got a great view.
"I wasn't expecting it to be as big and great as it was. We were told to take down our tents at about five in the morning, which we'd had up since about eight in the evening.
"Initially we'd put them up at about seven, but had to take them down because police said we had to wait an hour.
"Some of us slept, but with all the noise and it being quite cold and uncomfortable I just stayed up overnight.
"It was quite a sombre day, but a hell of a day overall. The procession was just absolutely amazing."
Matt said he didn't even realise he had taken the photo of Prince George until Monday afternoon.
He added: "I'm just a bit of an amateur photographer, so I borrowed a camera for the day to get some better photos.
"I'd seen Prince George and Kate go by and snapped a photo of their car, but it was only a very quick photo so I didn't think it would be that good.
"I only realised later when I was looking through the photos that George was pulling that face.
"It was quite a funny thing to get a photo of - especially as he's now second-in-line for the throne and his brother did the same thing at the Jubilee."
