Spending time with Kristen Stewart made Charlize Theron feel like a teenager again.

The 36-year-old actress plays Evil Queen Ravenna opposite Kristen, 21, as Snow White in the new movie 'Snow White and the Huntsman' and working with the young starlet made Charlize feel like she was reliving her youth.

She explained to Mexico's Vanidades magazine: ''From the moment we met there was this amazing chemistry between us. We had a great time filming that movie. I really hope people enjoy it. Filming it made me feel like a teenager, like I was 12. The movie itself is a very ambitious project, and to me playing Ravenna was a lot of fun.''

Although she felt like a teenager on set, Charlize was impressed by 'Twilight Saga' star Kristen's maturity and also her fighting skills.

She said: ''Kristen is only 21 ... I remember when I was that age. Her performance is fantastic. In fact, she's quite the fighter.''

Charlize has previously revealed Kristen put up a good fight in their big battle scene, saying: ''She was a good fight! The bitch brought it.''
