New best friends? Charlize Theron has developed a girl crush on her Snow White and the Huntsman costar Kristen Stewart.

“I really, really love that girl. I love that girl, like, I would jump off a building for that girl,” Theron, 36, told Access Hollywood at CinemaCon 2012 in Las Vegas. “She’s amazing, she’s amazing. She’s the real deal… [and] she gives really good back rubs.”

And Theron was equally impressed with the 22-old's acting skills on the set of their action-fantasy flick inspired by the Snow White fairy tale, which opens in theaters June 1.

“[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,” Charlize explained. “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.” 

The two costars also bonded on set over their love of cooking. 

"They're both really reserved, but they've had a few dinners together," a source told Us Weekly in December 2011 while the costars were filming. "They're serious cooks and like to compare notes."
