Fans are already used to seeing plenty of Pietro Boselli—the model and engineering PhD famously dubbed the world’s hottest maths teacher—but this photoshoot may be his boldest yet.

Fresh off a headline-making shoot with his brother that left very little to the imagination, the then-28-year-old appeared to push the boundaries even further in a collaboration with acclaimed fashion photographer Mariano Vivanco.

Vivanco shared a striking image from the session on Instagram, featuring Boselli seemingly posing completely n*de, with only a carefully placed cluster of orchids preserving his modesty. But eagle-eyed fans were quick to point out that the flowers may not have concealed quite as much as intended, sparking plenty of online buzz.

The picture has divided opinion, with some saying any flesh on show is merely the former Attitude cover star’s thigh; but from the right angle, it does look it could be a fraction of the world’s hottest maths teacher’s you-know-what.

Maybe desperation has made us obtuse to the reality of the situation. Either way, full-frontal or no full-frontal, he’s still acute-y.
