Thank goodness photobombing Her Majesty the Queen isn't treasonous or punishable by a stint in the Tower of London. Otherwise the Duchess of York's youngest daughter might be in a spot of bother:
Was Princess Eugenie determined to upstage her grandmamma? Or could she simply not resist the presence of cameras at Royal Ascot?
Either way, we confess we rather like it. And of course, young Eugenie is carrying on in fine celebrity tradition - just take a look at this little lot...
