Demi Lovato vs. Cher Lloyd vs. Rita Ora vs. Jessie J vs. Jade Thirlwall: Whose Blue Hair Do You Like Best? – Readers Poll

Demi Lovato and some British songbirds known as Cher Lloyd, Rita Ora, Jessie J and Jade Thirlwall of Little Mix have all dyed their hair blue in recent months... well, save for Jessie, who loves her colorful, sleek wigs. The question is, which of these ladies do you think looks best with blue hair?

Demi is the only American in this poll and the only songstress to hold off on going full-blown blue. Instead, the 'Made in the USA' hit maker opted to dye the lower half of her hair blue, giving her blond strands on top a nice, bright contrast. Then there's Cher Lloyd, who actually dyed her hair bright blue by accident. She was going for a more blackish blue shade, but her hairdresser ended up going full-blown electric blue -- it's a good thing the 'Want U Back' beauty can pull off this edgy look!

Rita Ora has also been seen with blue hair a few months back, swapping her usual blond shade for a turquoise blue. Her slicked-back blue 'do looks bangin', and the stylish 'Radioactive' songstress set yet another trend with these blazing blue locks. Unlike Rita and the aforementioned pop divas, Jessie J didn't quite dye her hair blue, but instead slipped on a blue bob wig. We think this color suits her, but then again, doesn't every shade under the rainbow?

Finally, we've got Little Mix darling Jade Thirlwall, and this Brit knows how to do blue hair right. Her long, lovely tresses look gorgeous in that shocking shade of blue. We also love how the 'How Ya Doin'' girl grouper blended in darker strands to make that vibrant blue just a tad more subtle.

So, who gets your vote for best blue hair this time around? Vote for Demi, Cher, Rita, Jessie or Jade below!
