Tyra Banks is a Harvard graduate!

Just when we though her head couldn't get any bigger, Banks is currently congratulating herself for completing an Executive Education program at Harvard Business School.

The America's Next Top Model creator and host was busy sharing the exciting news via Twitter Thursday. Smiling ear2ear on the Harvard Business School campus w/ my diploma! Tnx 2 my fab photographer mama 4 the pic!, she tweeted, along with a link to a photo of herself displaying the certificate in front of what appears to be a building on the Harvard campus.

She also tweeted a blurry photo of herself picking up her certificate onstage at the graduation ceremony, wearing a little black number and stiletto heels. On stage at my Harvard Business School graduation! Lil blurry but SUCH an exciting moment 4 me & wanted 2 share w/u!

Banks completed the Owner/President Management Program offered through the Executive Education branch of Harvard Business School. From the Harvard Business School website:

Focused on corporate growth, leadership expertise, and financial success, OPM is an unparalleled opportunity to enhance your business skills, innovate with other talented executives, and prepare for the new challenges that lie ahead. Whether you seek a more global perspective, better ways to seize opportunities, or greater insight into go-to-market options, OPM can help you realize your company's potential-and your own.

Presented as a three-week session each year over three years, OPM provides the skills, tools, and network you need to become a more accomplished leader.

There are no formal educational requirements, but the program is geared to successful entrepreneurs.  According to the program description, candidates must be actively involved in running the business and hold a significant equity stake in their firms.

Earlier this week, Tyra spoke to Bloomberg Businessweek about what she took away from the program.

Harvard is all about innovation and being first to market, she said. It's something I'm constantly bringing back to my team, whether it's my soldiers or my generals. I give them challenges and homework and brainstorming sessions to bring the culture that I'm learning at school into my own business.

She also said that the program has helped her understand how certain celebrities become successful.

I also look at what Lady Gaga is doing and think it's near-genius, Banks said. Had I not gone to Harvard, I'm not sure I would have seen it as a marketing play. I would have just said, 'Oh, she's popular.' Now I see how smart she is. It's a true, clear, executed plan.

Though Tyra already as her diploma, her time at Harvard isn't over yet.

My marketing professor Rohit Deshpande is now doing a case study on my business, so I'm now going to be part of the Harvard Business School curriculum, she told Businessweek, adding that she'd been invited to sit it on the presentation of the case study, where these guys are going to come and tear apart her company.

Banks was recently named the second richest supermodel in the world by the Daily Mail.

Her Wikipedia page has already been updated to list Harvard as her alma mater.
