Vacuous
I can't tell if that's actually Paris Hilton or if it's a wax statue of her likeness. She is that vacuous. I suspect a wax statue is probably smarter, though, and less disease ridden. More from Kristen Cavallari's birthday party:
Vacuous: Devoid of matter; empty. 2. Lacking intelligence;
stupid. 3. Devoid of substance or meaning; inane. 4. Devoid of
expression; vacant.
