The 'Heart Attack' singer had just woken up when she grabbed her phone and filmed a short video, before sharing it with fans on Keek.
She added the caption: "Soooo sleeeeeepy... Good morning!!!"
Demi can be seen rocking tousled bedhead hair with a rather messy fringe, whilst ditching her foundation and mascara and going au naturel.
But we reckon she still looked gorgeous - who wouldn't want her clear, even complexion and naturally bold brows?
And it's not the first time the starlet has gone make-up free. Earlier this year she arrived to a US film appearance without a scrap of slap in sight, and she also posted a fresh faced selfie on Twitter in April.
She added the caption: "Ladies, be brave today… take off your make-up and stop using those filters!! WE are beautiful!!!"
