Watch: Spend 24 Hours With 'Hottest Math Teacher in the World'

Pietro Boselli became e-famous last year after a student snapped a pic of his math teacher and put it on social media. It was later revealed the instructor is also a male model (duh).

Boselli, dubbed the "world's hottest teacher," recently started up his own YouTube channel and created a video with Vogue Homme Paris where the fashion magazine follows the 28-year-old Italian model around for 24-hours during Milan's men's fashion week.

The new video comes about a month after Armani announced Bosell is the new face for their sporty EA7 line.

As depicted on his Instagram, Boselli, who has a Ph.D. in mechanical engineering, spends a lot of time working out and looking fabulous (with and without a shirt). For its video description, Vogue Homme writes:

With 1 million Instagram followers to his name thanks to his students taking pictures of him in class, if male model Pietro Boselli is not the sexiest math teacher in the world, then he certainly has a strong case. Vogue Hommes spent a day with him, at Milan Menswear Week.
