Banks has brains!

Tyra Banks has been attending Harvard Business School since last year.

Enrolled in the Harvard Owner/President Management Program, the model-turned-mogul, 37, is intent on building her business savvy. “It’s pretty exclusive,” she told CBS News.

Pricey too. Banks is shelling out $31,000 a year to spend just three weeks on campus for three years. “But I feel like it is so, so worth it,” she said. “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.”

The ex Victoria’s Secret stunner has been interested in going back to school since dropping out of Loyola Marymount University to purse modeling at age 17. “The day I put college on hold because I got discovered….was one of the most difficult decisions of my entire life,” she said.

So how do classmates react to the model-student? “I get mixed reactions,” she said. “There are little facial expressions….The chin goes back, like, ‘Really?’…it’s like why is a model going to Harvard? But that’s actually a good thing, because when people have low expectations, you’re just constantly going, ‘Ta-da!’ And they’re like ‘Wow.’ It doesn’t take a lot to wow them.”
