Demi Lovato Debuts New Short Hair (PHOTO)

Demi Lovato is making some changes in her life -- to her hair.

Lovato debuted a new, short haircut in a tweet to fans on Tuesday night, Us Weekly noticed. The 20-year-old singer chopped off her long locks for a shoulder-grazing style complete with side-swept bangs. The last time the former Disney star had short hair was during her "Sonny with a Chance" days.

Of course Lovato might not have actually cut her hair. It could be that she just removed her extensions -- you never know with celebs these days. Either way, we're digging the new easy, laid-back look.

The "Heart Attack" singer has switched up her hair a bunch of times, going from blonde to pink, from bangs to no bangs, from red highlights to blue to ombre. "I love changing my hair a lot -- I think it's fun," Demi once told the Allure magazine. She held off on the wild colors in her early audition days, but lately has gotten more adventurous: "You know you've made it when you can dye your hair blue."

It's also worth noting that a drastic hair change can signal another shift in one's life. Something you want to tell us, Demi?
