We're not sure why this has become such a thing, but celebs around the world have started showing off how crazy they look wearing facial cloth masks... and we like it!
Kelly took to Instagram on Sunday (24 May) like many A-listers before her.
"Just discovered why you should never have a serious convo while wearing a face mask! Hilarious!" Kelly posted.
A few days earlier, Myleene Klass showed off a similar (although slightly more glamorous) snap, while treating her under-eye area to some skin loving masks.
We've also seen similar selfies from the likes of Lady Gaga, Lydia Bright, Kelly Brook and Rita Ora – and that's just naming a few!
Kelly posted another selfie earlier that day showing off her glowing, natural skin after a workout session at the gym. And her make-up free complexion proved she's obviously doing something right in her skincare routine.
"I love this pic this post gym selfie I took by accident!" she wrote, alongside the picture (above).
"It drives me nuts when you turn your camera on & all you see is your own big face on the screen!"
So, what's all the fuss about these cloth facial masks, also known as tissue or sheet masks?
Well, as with lots of innovative skincare products, they were born out of Asia and come soaked in potent, skin-loving ingredients. After sitting the mask over your skin, the cloth works by warming up those ingredients, trapping them onto your skin and allowing them to penetrate much better than something like a serum.
Sold? With Kelly O's complexion as proof of how great they are, you should be.
