Actress says she's more concerned about not looking crazy

Scarlett Johansson says she worries about people thinking she could be a little crazy.

When the actress goes out, she’s more concerned with appearing lucid than sultry.

‘I don’t normally think about being sexy,’ she tells Cosmopolitan. ‘I think: “Do I look presentable? Do I look sane?”’

Scarlett, 23, is engaged to actor Ryan Reynolds, 31.
