Demi Lovato is known for frequently changing up her hair color so it was no surprise when she showed up to The Tonight Show With Jay Leno with neon blue locks! The color seemed to be quite fitting for her performance of her latest single, "Neon Lights." Demi also tweeted a mirror selfie of her new hair with the caption "LIKE NEON HAAAIIIIIRRRRR!!!!"
