Celebs in Glasses
Whether necessity or fashion, eyewear is in.
Today, (March 14) may seem like a regular Monday, but it isn’t just any ol’ day — it’s National Pi Day!

While not everyone can be a regular Albert Einstein (who was actually born on March 14 … go figure!), there are those celebs who have much more going on beneath the surface of their gorgeous skulls.

Case in point:

People Magazine reports that model Tyra Banks has been taking classes at Harvard Business School for the last year! She already has a glowing empire, but felt the need to keep herself mentally stimulated and wanted to expand:

“In order for my company to grow and be the best, and to reach these women, and to serve them, I needed the best. So I went to the best.”

To celebrate Tyra’s latest scholastic venture as well as this fantastically nerdy day, Celebuzz compiled a list of the smartest stars out there, some of which may surprise you!

So check out the gallery and tell us on Twitter or Facebook — which smart celeb is your fave?
