A lot, actually, as the singer took to Instagram earlier today to share a selfie sans a single stitch of make-up with her 17.9 million followers - brave!
It looks like Dems spent her morning working up a sweat in the gym in the super-cute snap which shows her rocking a halter-neck workout top and a comfy tee, giving us a little glimpse of her cleavage.
The brunette beauty swapped the slicked back look she sported at the Sirius Radio birthday bash in New York last week for something a bit more pared back. In fact, it looks like Demi ditched the hair product all together and let her glossy cropped locks fall to one side for a natural, 'I woke up like this' vibe.
And can we just take a second to marvel at her clear complexion? Demi certainly didn't give the Perfect356 picture editing app a whirl before posting her selfie (we're looking at you, Kim Kardashian) as she showed the world her cutesy freckles.
The star captioned her snap with the hashtag "nomakeupmonday" and her fans jumped on board to praise her for giving the slap a break.
One user commented: "It doesn't matter if she wears make-up or not, she's still beautiful!" with another saying, "You're gorgeous even without make-up."
Demi is the latest celeb to go barefaced on Instagram in the past few days after Kylie Jenner and actress Sofia Vergara both shared flawless fresh-faced snaps.
