We have no idea why Giuliana Rancic thought publicly mocking an 18-year-old dread locks was a good idea -- but she did it anyway!

The E! star poked fun at K.C. Undercover actress Zendaya and her Oscar hairstyle, which consisted of some fierce dread locks, on Monday's episode of Fashion Police. On the show, Rancic said that star must have smelled of "patchouli" and "weed."

Understandably so -- the teen star did not take too kindly to the thoughtless slams about her hairstyle, which was inspired by Lisa Bonet's hairstyle on A Different World. Zendaya took to Instagram to post a well thought-out response to the digs.

"There is a fine line between what is funny and disrespectful," she wrote. "Someone said something about my hair at the Oscars that left me in awe. Not because I was relishing in rave outfit reviews, but because I was hit with ignorant slurs and pure disrespect."

Hell yeah!

We don't even know what Rancic is talking about -- Zendaya looked absolutely fab!
