Ok, so it was a definite thing on the Alexander Wang Autumn/Winter 2014 catwalk during New York Fashion Week plus Lady Gaga and Miley Cyrus are advocates of the look (that W Magazine cover) but is going eyebrow-less really going to catch on? *Widens eyes*
Perry posted this photo on Instagram with the caption "BAUSS BISH BB", which we're translating as "boss b*tch blonde brows". Surely?
This is one of those trends that is definitely going to divide opinion, just like the slime green hair that Perry's working right now - it's just not for everyone.
Here's a look back at Miley doing bleached-out brows...
The thing is, Perry does pull off this whole futuristic vibe.
It's not just the bleached blonde brows either, the double braided top knots and slicked down, curled baby hair in the front of her hairline is pretty out-there too.
Side note: if you're all about following the latest catwalk/ celeb beauty trends then do it at home, with loyal friends. And maybe avoid anything slightly selfie related until you've really mastered the look. And have the kooky ensemble to team it with a la Perry.
Katy's metallic nails and the OTT luxe lashes? Now that we can get onboard with.
