(Cover) - EN Showbiz - Kristen Stewart says when Charlize Theron walks into a room "everyone knows it."

The actress co-stars with the Oscar winner in Snow White and the Huntsman and they seem to have developed a strong friendship.

In a chat with Interview magazine, the Twilight starlet says that Charlize has real presence.

"She is unlike anyone I've ever encountered," Kristen gushed. "She is one of those people who walks into a room and everyone knows it."

"She's a f***ing movie star. It's funny too because she always says, I'm not really a performer.' But I'm like, Yeah, not at all.' [laughs] She's an actor and a performer."

The feeling is very mutual as Charlize has also spoke fondly of her time working with Kristen.

"I love that girl, like, I would jump off a building for that girl," Charlize told Access Hollywood. "She's the real deal and she gives really good back rubs. She's got a tremendous amount of talent."

Kristen added that they get on so well because they are "both absolutely willing to hurt ourselves to do what it takes to get the right feeling, and not all actors are like that." (C) Cover Media
