Happy Pi Day! Here's Some Smartypants Celebs (PHOTOS)
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!
