The 21-year-old model flaunted her enviable disappearing underarm while her personal trainer revealed how she gets her "sculpted physique" - probably the most unfortunate choice of phrase considering the circumstances.
This is a just a wild stab in the dark but is her secret over-enthusiastic Photoshopping?
Scroll for picture.
Is Harper's trying to tell us something? Is it no longer enough to sweat buckets in the gym in a bid to own an eight inch thigh gap? Must we now add a skinny armpit into the perfect body criteria? How do you even work out your armpit? Shit.

It's time to take a stand against this could-be trend we shall henceforth dub the "skinny-pit". Ladies, don't cave into the pressure - your armpits are beautiful as they are.
Sound ridiculous? Yeah we thought so. But perhaps this painful-looking photoshop fail is enough to open our eyes to just how enhanced the images we see each and every day really are - because we highly doubt Kate Upton has armpit hangups.
