The 'Skyscraper' singer initially hid her neon pink hair under a grey Dallas Cowboys hoodie while leaving a hotel on Monday (10 March), but later showed off the eye-catching 'do in all its glory.
Loving the matching lips and hair!
Never one to shy away from interesting new looks, 21-year-old Demi dyed her locks pink in January, before shaving the side of her head earlier this month.
Probably not a look we could rock ourselves but Demi looks pretty fab, doesn't she?
Former US X Factor judge Demi is currently on her 'Neon Lights' tour in the US, which features our very own Little Mix as the support act.
She arrived in New York over the weekend ahead of tonight's show in Uniondale, and found time to make a guest appearance on yesterday's The Tonight Show Starring Jimmy Fallon.
Demi joined Steve Harvey and Kristen Bell for a game of Pictionary and had the unenviable task of having to translate the phrase 'butt dialling' into a picture.
Remarkably though, she did it – and quickly! It didn't take too long for her partner Jimmy to guess correctly.
We know whose team we want to be on next time the Pictionary cards come out!
