The South African actress stars alongside the Twilight beauty in new movie Snow White and the Huntsman and she admits she loved working with her, mostly because she was an excellent back rubber.
She told Access Hollywood: "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 and you know, I think you can have talent, but if you don't have tenacity and moxy ... she's bad ass."
Charlize - who plays the evil queen in the movie - recently revealed she liked to go to work with a sense of fear.
She said: "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, 'Oh, f**k, 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.
"Nothing's kinda like, 'I can do this with my eyes closed' and I think that is ultimately what every actor wants, something that challenges you to that point."
