REESE Witherspoon says it was a “nightmare” having to ride a horse in her new movie Water for Elephants.

The actress admits wearing tights while on the animal hurt her legs!

“I trained to ride an elephant for about three months before filming but I was always wearing jeans,” says Reese.

“So when I showed up on set and I actually had to get up there in tights I was like ‘Ouch!’ My legs felt like they were getting stabbed by little needles. It was a nightmare.”

Reese recently talked about working with Robert Pattinson on Water for Elephants.

I am so lucky. He’s so amazing and wonderful and sweet and just the nicest guy too, so you can just add that to the soup,” she revealed. “I mean, he’s just so good looking and he’s a really nice person.

“We’ll probably just laugh the whole time, because all we do is just laugh and joke around.”
