This can't be proper royal etiquette around her Majesty!
Princess Eugenie stepped into Queen Elizabeth II's spotlight during her appearance at day one of the Royal Ascot.
The two were accompanied by the Prince of Wales and the Duchess of Cornwall and appeared entertained by the race from the Royal box.
The 23-year-old young royal, who looked chic in an all-black ensemble, moved in front of the Queen just before a photog snapped a pic of the two together.
Princess Eugenie seemingly blocked the shot while waving to the cameras.
The Queen is just the latest in a slew of famous faces to be photobombed. Everyone from Johnny Depp to Donald Trump has taken part in the hilarious hijinks.
