Some models are really stereotypically silly but some are actually quite intelligent. I think Christy Turlington has an Arts degree (Comparative Religion and Eastern Philosophy majors) but Gisele doesn't seem to be the sharpest tool in the shed (although I could be wrong). Jessica Simpson still holds the title for the chicken/tuna comments (although she isn't a model).

Lily Cole got into Cambridge after getting straight As at school. I tend to forget how young she is.
