The 'Heart Attack' singer, who is currently on her 'Neon Lights Tour' shaved off a chunk of her hot pink hair from the left front section of her head - just because she felt like it!
Demi showed off her new hairdo by posting various selfies to Twitter, in what she called a "shaved head photo shoot".
The 21-year-old first posted a photo of her chopped off locks with a hair clipper placed next to it.
Captioning the photo, she said: "So.... This happened...... Oops. #NEONLIGHTSTOUR."
Demi also wrote the acronym "IDGAF", which is short for "I don't give a f***."
In another snap, Demi pulls a pose a she sports a personalised black cap, also commonly known as snapbacks. She said: "Rocking my fan-made LOVATO snapback... #NEONLIGHTSTOUR."
After showing it off at all angles, Demi said: "Last selfie of my shaved head photo shoot. #NEONLIGHTSTOUR."
We must admit, if anyone can rock this look, it's Demi!
Demi is known for regularly changing her hairstyles and experimenting with colour, so we're not too surprised that she fancied a change again.
Back in January, Demi unveiled her newly-dyed pink hair after previously having bright blue locks.
