Brows have become 'the' thing over the past few years with Cara Delevingne and Lily Collins slaying the brow game.

And apparently now, the new thing is the 'under brow' which Instagram and social media beauty types are going cray-cray for.

Gigi Hadid nailed the look at the Giambatista Valli AW16 fashion show recently, basically just having a second colourful brow right under her real ones.

Then, cos it's Gigi, the world went mad.

Seems simple though right?

To get the look simple comb your own brows and draw a colourful or glittery line with eyeshadow, liner or gel, directly under them.

Donezo.

We're off to try it at our Sunday family dinner. Lols.
