Tyra Banks should probably pick out a nice pencil skirt and grab her most fashionable notebook. At the age of 37, the former supermodel has elected to go back to school. She’s said to be taking an executive education course for entrepreneurs at Harvard Business School.

The former talk show host is the founder and head of Bankable Productions which produces hit TV shows like “America’s Next Top Model” and “True Beauty.” With all of her businesses combined, her brand earns an estimated $90 million a year.

If you think beauty is all that Banks does, think again. She recently signed a deal with Random House to publish three books this year. Talk about Miss Independent!

According to Clutch magazine, the last time Banks was in a classroom was 20 years ago — it’s never to late to go back to school.
