The 36-year-old actress stars alongside the "Twilight" star in the new movie and Theron said she loved working with her, reported Femalefirst.
"I really, I really really love that girl. I love that girl, like, I would jump off a building for that girl. She's amazing. She's the real deal and she gives a really good back rub.
"Kristen is the kind of actor that I like to be around because there's nothing she'd really stop at in order to do the job. She's got a tremendous amount of talent," Theron said.
Theron, who plays the evil queen in the new fairy tale adaptation, recently said she liked to go to work with a sense of fear.
"I do have a sense of fear every day going to work, but I think it's something that I like. I mean I do like the feeling of waking up on my own, having this moment of like, 'I hope I can do this today' because it makes you realise that you're working with material or you're working with a director or you're working with a cast and they're keeping you on your toes."
