UPDATE (October 24, 2013):

Looks like Demi's staying blue. In a new photo shared via her Twitter, the pop princess shows off her vivid hair in a set of four photos. "Blue hurr, don't curr..," she writes. Lookin' good, Dems! 

ORIGINAL STORY (October 2, 2013):

We think we had a heart attack, you guys. Our spirit animal, Demi Lovato, has gone through plenty of hair transformation in her 21 years on earth and has even sported streaks in a similar shade, but we think this may be the first time she’s gone completely blue!

Demi appeared on The Tonight Show with Jay Leno on October 2 to perform. She is also out promoting the current season of X Factor and her upcoming Neon Lights tour. (How she found the time to change her hair color with all that going on is beyond us.)

Well, some of those neon lights seem to have made their way into Demi’s hair, which is glowing with an electric shade of blue. So punk rock!

We’re not sure if the look is permanent or here today, gone tomorrow, but we have a sneaking suspicion it’s the latter. There’s something about the color that looks like it's probably a DIY job — maybe with a colored hairspray or hair chalk. Did Demi blue herself? (Sorry not sorry.)

Whatever color she dyes her hair, Demi looks flawless, so you won’t hear any nay-saying from this camp. While it’s maybe not our favorite look on Demi, we’re not too worried. Her hair is as inconstant as the wind — the color changes faster than the leaves on autumn trees.

What do you think of Demi’s most recent hair transformation?
