Charlize keeps K-Stew on her toes

Kristen Stewart has admitted she wants to stand on tip-toes when she\'s around Charlize Theron. The Twilight actress, 22, gushed about her Snow White And The Huntsman co-star, 36, at an MTV preview screening of the film. She told E!: \"I want to stand on my tippy toes when I\'m around her. She\'s mad intimidating. Most people would make you feel really bad about yourself when you\'re intimidated by them, but I feel so great around [her].\" Kristen, who plays Snow White to Charlize\'s Queen Ravenna in the film, added: \"She\'s awesome. And she\'s hilarious - she\'s so fast and quick.\" But she added that she didn\'t think she or co-star Sam Claflin would be babysitting for Charlize\'s son Jackson any time soon. \"I don\'t think she should trust either of us,\" she joked.
