The 22-year-old star detested the scenes on horseback in her latest movie `Snow White and the Huntsman` - in which she plays the titular character - although she thought it was "cool" to watch others look "uncomfortable" around the animals.
She said: "Riding a horse was the worst part of the movie. The dynamic between horse and rider is not for me.
"I`ll happily watch a horse run around a pasture, I`ll even run with him but I hate ridinghorses. But it`s cool to watch people genuinely uncomfortable on screen."
Kristen`s co-star Sam Claflin - who portrays Prince William in the fantasy motion picture - also had difficulty riding a horse in the film as he fell off while riding alongside Chris Hemsworth (The Huntsman).
But instead of helping Sam, who was dressed in full armour at the time, the `Avengers Assemble` actor decided to speed off on his horse to "save the scene".
Chris explained to BANG Showbiz: "At one point Sam and I had to ride in on horseback and we were supposed to jump off the horses and we had never practiced this before and were only told just before we shot the scene.
"So, Sam jumped off and got his foot stuck in the stirrups because he was in full armour and he ended up on his back and couldn`t get back up and I was going to go help him but I remember thinking `Keep going, save the scene` "
