Well, Cindy Crawford did drop out of school to pursue her modeling career, but as you cited...

 Quote:
Crawford was her high school class’s valedictorian, graduating with a perfect 4.0 GPA.


I'd also argue that her ability to remain at the top of her career for 3 decades also demonstrates considerable intelligence.

But I admittedly would not want to make that same argument for female celebrities like Lindsey Lohan, Whitney Houston, or Britney Spears.
Although as far as I know, none of these were valedictorians of their class.



Although one I can think of, Winona Ryder, was!
