*Former supermodel turned TV producer and talk show host Tyra Banks is stepping up her game once again.

The Boston Herald is reporting that she is enrolled in an executive education class at Harvard Business School specifically for entrepreneurs.

Banks has turned her successful modeling career into a $90 million brand with the creation of her entertainment company, Bankable Productions.

The Southern California native graduated from high school in 1991 before relocating to Paris to become a runway model.

Banks, 37, and a Daytime Emmy award winner and author, has also signed with Random House to publish three novels this year. In addition, she produces The CW’s “America’s Next Top Model,” ABC’s “True Beauty” and her daytime talk show.

To show that she’s got school fever, she tweeted pictures of herself wearing a Harvard Business School sweatshirt to bed.
