Jessie J's Bold New Haircut Leaves Her With Very Little Hair

Jessie J changed her look up big time over the weekend, and it had nothing to do with Halloween. After posting old pictures of her with a shaved head back in 2013 and reminiscing over the style, Jessie took the plunge -- again -- and shaved all her hair off.

Jessie posted this picture of her buzzed-off hair and all-over face paint saying, "@joshmadden costume was sick! ?Shaved my head last week (I guess you might notice)" Oh, we did.

And we should have seen it coming, too. In addition to sharing old pictures of the 'do days before the big reveal, she also posted a pic of her hair on the ground in the shape of a smiley face with the caption: "I'm a rebel on the sly #girlpower #feelingfree ???"

Well now we know what to expect the next time Jessie's Instagram gets a little too hair happy.
