Demi Lovato
has said goodbye to some of her long locks! 

The singer posted a pic of her newly shaved tresses via Twitter on Tuesday. "IDGAF #NEONLIGHTSTOUR," she captioned the candid snap of her post-haircut.

FYI: "IDGAF" stands for "I don't give a f**k."

Earlier in the day the "Skyscraper" songstress posted another photo teasing her new 'do. 

"So .... This happened ..... Oops. #NEONLIGHTSTOUR," she wrote along with a shot her her pink ponytail next to an electric razor. 

We think if anyone can pull off the half-shaved style it's definitely Demi! What do you think of the 21-year-old's latest look?
