As is royal tradition, Kate Middleton arrived at this year's Trooping the Colour celebration in a horse-drawn carriage.
Her husband Prince William, however, rode into the ceremony on horseback - something a royal expert has revealed it's unlikely we'll ever see Duchess Kate doing.

Kate, it seems, is one of the few members of the royal family who doesn't ride a horse.
And although it has been widely rumoured that Kate is allergic to horses, according to Marcia Moody, the author of Kate: A Biography, the reason the Duchess snubs the hobby is because it simply isn't in her blood.
"Kate doesn't ride, purely because she didn't do it growing up," Marcia told Town & Country.
"William and Harry were taught from an early age, but the only time they ride now is for polo - they don't go off on hacks like the queen always has."
While Kate isn't a fan of horse riding herself, it is something she has encouraged her kids take part in.
They said: "William and Kate were keen to get George on a horse once he was walking confidently.
"George loved his first ride – he was led around a paddock on a rein and shrieked with delight. William and Kate were both there to watch."
Queen Elizabeth II herself is also a keen equestrian, with the monarch arriving at the Trooping the Colour on horseback many times over the years.
Her Majesty even braved the British rain in 1982, as the ceremony was held in the middle of a downpour.
