Brains and brawn! The modeling world just got a whole lot hotter with the addition of "the world's hottest math teacher."

Pietro Boselli, an academic eyeful, already has a strong legion of fans on Instagram due to his dashing good looks and rock hard body. Now, more people are going to get their fill of the mathematical brainiac after he signed a modeling deal with Armani.

After riding my first wave! 🏄

Pietro, dubbed "the world's hottest math teacher" by his 856,000 Instagram followers and the media, has been blowing up Instagram feeds and giving new meaning to being "hot for teacher" ever since a student realized that her professor had an awfully attractive double life.

"That moment when you realized your maths lecturer is one of the top designer model," the Facebook message read, with pictures showing a side by side image of Pietro in class and in an ad campaign. "#OnlyatUCL #UCLengineering #MechanicalEngineers #ModellingandAnalysisClass #Bromance."

The University College London PhD has now reportedly inked a deal to serve as the face of Giorgio Armani's athletic-inspired EA7 line, something that should suit the pretty-faced teacher just fine, as he's said that he's addicted to training and he often posts videos of himself performing his daily workouts.

And, this isn't' the first time that he has modeling for the luxury brand. In 1995, as a six-year-old, he was the face of the Armani Junior campaign, which he did for five years before being scouted and signing in Milan with a talent scout agency.

Unfortunately for Pietro's admirers, he took a seven year hiatus from modeling, but was called in for a test shoot with Armani at age 18. That was the beginning (again,) as he was an exclusive runway model for Armani, walking in all of the brand's shows, all the while mainly remaining focused on academics.

According to Pietro's LinkedIn account, he worked as a teaching assistant and then lecturer at UCL until June 2014.

Two smiling guys 😄

We said it once, but we'll say it again, has the term "hot for teacher " ever been more applicable! Have students ever been more excited to actually go to class and learn math?

Had the pleasure to meet @marianovivanco today! 💥📷
