'Skyscraper' singer Demi, 21, had been sporting neon pink locks since kicking off her 'Neon Lights Tour' earlier this year, but opted for a change last night.
Showing off her newly-dyed brunette barnet, she told fans: "Gonna give my hair a break."
Hmm… some Demi fans aren't so convinced though, given the former Disney starlet's love for switching up her look.
One tweeted, "Real question, how long will this last?" Another advised: "Back to a natural colour. Beautiful darling. Let it grow out now before you do anything else to it."
Sensible words, perhaps, given that Demi's hair has been almost all the colours of the rainbow! In addition to her recent pink hue, she's tried out brown, black, blonde, red and even blue.
Demi's tour runs through until 17 May with stops across the US, Canada, Brazil, Argentina, Chile and Mexico. She was supported by Little Mix at the start of the tour.
She'll then jet over to the UK in June to perform a one-off show at London's Koko on 1 June.
