Demi Lovato debuted cobalt-blue hair on "The Tonight Show with Jay Leno" on Wednesday.

The world has seen the "Heart Attack" singer with blonde, auburn, raven and even pink locks before, so she clearly likes experimentating with her hair color. Lovato even joked about her ever-changing hair during an appearance on "The Ellen DeGeneres Show" earlier this year.

"You've heard I'm bipolar, so I change my hair a lot," Demi told Ellen.

And what a change it was for the former Disney darling to get such a drastic dye job!

The pop singer showed off her  transformed tresses on television for her fans everywhere. As she performed her song, "Neon Lights," Demi commanded the crowd. Even though she rocked the electric hue, the songbird was definitely not feeling blue. 

During her dramatic hair color debut, Demi complemented the vibrant color with a black smokey eye, bright blush on her cheeks and black nail polish. And the songbird's skin was very tan, enhancing her blue tresses even more. 

Demi also rocked a leather motorcycle jacket and black leggings for a very stylish, edgy look.
