This is the adorable moment a young boy took off his top hat and approached the Queen for a handshake as she spoke with Dubai royalty at the Epsom Derby.
Little Mohammed bin Ahmed Jaber Al Harbi looked dapper in a top hat, white tie and tails as he walked up to Her Majesty as she stood in the paddock at Epsom Racecourse on Saturday.
The monarch, wearing a flowery dress, yellow coat and sunhat, was talking with Dubai's ruler, Sheikh Mohammed bin Rashid al-Maktoum, when the youngster approached.
The young boy is believed to be acquainted with the Dubai royal family and is often pictured with Sheikh Mohammed's son, Crown Prince Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum.
Sheikh Hamdan, the Middle East's equivalent of Prince Harry, uploaded the endearing video to Instagram alongside the caption: 'Nothing defines respect better than a proper handshake! Epsom Derby with Queen Elizabeth II.'
The footage shows the small boy approaching the 89-year-old monarch as she peruses a racecard at the sun-soaked racecourse.
He then takes off his black top hat before stretching out his hand to the Queen. Her Majesty reciprocates the gesture and shakes the youngster's hand before he walks off with a big grin on his face.
The Queen, who is a big equestrian fan, attended the Derby with her husband Prince Philip, racing adviser John Warren and Princess Michael of Kent.
Mr Warren could be seen in the video smiling and laughing as young Mohammed carried out the loveable gesture.
The youngster is believed to be part of the Dubai royal family and is often pictured on social media with Sheikh Hamdan, who describes the little boy as his 'best friend' in many posts.
Sheikh Hamdan is the heir to the emirate of Dubai and is one of current ruler Sheikh Mohammed bin Rashid Al Maktoum's 12 children.
He attended the annual flat racing meet with his father, who is also Vice President and Prime Minister of the UAE.
The royals were also joined by Sheikh Mohammed's wife Princess Haya and all three were welcomed into the Queen's stand where they spoke with Her Majesty.
According to Sheikh Hamdan's website, the Dubai and British royals exchanged talks on UAE and UK relations, as well as horses participating in the day's racing.
Sheikh Hamdan, 32, known as Fazza to his friends, will take over rule in Dubai in the future, and claims a stint at Sandhurst taught him the benefits of 'self-discipline, commitment, virtue and responsibility'.
The prince is a keen rider, much like his father who owns the Godolphin racing team - which is one of the most famous racing establishments in the world.
Action man Hamdan is also an avid diver, amateur skydiver and enjoys writing romantic poetry. He also has a well-known love of animals.
The Dubai monarchs joined the British royal family at Epsom racecourse for the 236th running of the Derby.
Well turned-out crowds enjoyed an afternoon of sunshine as racing at the annual flat meet got underway.
Many racegoers enjoyed picnics and champagne lunches while soaking up the atmosphere at the top-class event, which boasts a formal dress code.
All eyes were on Frankie Dettori who romped to victory in the £1.34million Investec Derby on favourite Golden Horn.
The Queen showed her delight at the victory, while Prince Philip struggled to watch as Golden Horn lingered towards the back of the pack before outclassing the other horses and storming across the finish line.
