The 37-year-old recently enrolled herself there to learn new skills in how to best run her business.
Speaking on Late Night with Jimmy Fallon, Tyra said she was shocked at first to learn she would be living in 'mandatory' dorms with the other students.
She said: 'Yeah we do live in dorms. I have my own room, we don't sleep in the same room. So I do have my own bed in my own room but we share a living room, a kitchen, a study area.'
Asked why she didn't get an apartment, she said: 'No it's mandatory dorms.
'I freaked out! In the beginning I was like: 'Yes, I'm going to Harvard Business School and, you know, it's executives. And I'll be at the Four Seasons down the street'.
'And they were like: 'Girl, you're going to be in the dorms!' I was like: 'What?!' I freaked, freaked, freaked out! And now I wouldn't have it any other way.
'Now it's like summer camp. Every time a term ends I get withdrawal and I get attitude for like a month because I miss my friends, I miss my professors, I miss living in the dorms. It's like a bubble.'
