Smart celebrities might seem like a contradiction in terms, but that's not entirely fair.
The two #things aren't mutually exclusive, and there are actually some pretty clever famous people.
Many have studied at an advanced level, and some have a very high IQ.

1. Lily Cole
Model Lily Cole clearly has plans for her future, which is smart when you're in a profession based on your looks.
Not only is she moving into acting (yes, the old model-turned-actress cliche), but she's also obtained a first-class degree from Cambridge University.
