Zendaya: former Disney star, current singer, dedicated no-makeup selfie activist, eternal anti-hair-shamer.

Previously, Zendaya was responsible for the anti-hair-shaming heard round the world when she called out Fashion Police host Giuliana Rancic's racist comments about her dreadlocks. (Brief recap: Rancic said they probably smelled like "patchouli" and "weed").

Now, Zendaya is once again standing up for her hair against critics (or more like, rude people on Twitter...let's call them what they are). Last night at the BET Awards, she debuted a new pixie-cut wig. She also wore a crystal-covered shirtdress and looked cool as hell. But apparently some people didn't like her new hairstyle, and also never learned the essential life lesson, "If you don't have anything nice to tweet, don't tweet anything at all."
