The Royals love horses and the Queen rides regularly. But, Middleton bucks the trend, because she is allergic to horses, reports the Daily Star.
Middleton's allergy became public knowledge after Australian author Kathy Lette referred to it in an interview with Reader's Digest.
In her interview, Kathy recalled a polo match in which she found Middleton sitting alone in a tent intently watching William play.
Lette asked her: "Why don't you play polo yourself?"
Middleton replied: "I'm allergic to horses." (ANI)
