From rapping baddie to pop-punk cutie, Machine Gun Kelly has evolved right before our eyes … and now, he’s adding another layer to his ever-evolving persona — college professor!

That’s right — the “Cliché” hitmaker headed to Harvard University this week to give a lucky business school class a lecture. He shared several pics of his visit on Insta, joking that “harvard has a new professor” in his caption.

It’s not clear what he taught — the business of the music industry might be a good guess — but he certainly looked the part, looking dapper in gray trousers and a plaid dress shirt. He layered his smart ‘fit with a brown leather jacket and accessorized with a bedazzled silver necklace and a maroon and gold tie with Harvard’s logo. Oh, and you can’t forget his “lost americana” — his most recent album — baseball cap.

He seemed to be a hit with students … he had them laughing at one point as he nearly cursed when his chalk broke while he was writing on the board. Can’t take the rocker outta the man!
