Kristen Stewart isn\'t convinced that her good friend Charlize Theron would allow her to babysit. Charlize adopted her baby boy Jackson earlier this year. Kristen and co-star Sam Claflin both act alongside the South African actress in upcoming fairy tale film Snow White and the Huntsman. The pair doubt that they\'ll ever get a request from Charlize to look after her son Jackson.\"I don\'t think she should trust either of us,\" Kristen laughed to E! Online. \"I don\'t think she\'d trust us with the kid or even her dogs,\" Sam joked. Kristen and Sam are deeply impressed by Charlize\'s presence. \"I want to stand on my tippy toes when I\'m around her,\" Kristen smiled. \"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].\"
