Wow! What do you think of Demi with a short, straight bob?

She shared this new look on Twitter followed by :"I miss my black hair :("

But wait, would Demi REALLY cut off all her hair? No. She then tweeted: "It's just a wig that I got today!! Hehe... Don't freak ;)"

Do you think she looks better with short or long hair?
