Zendaya killed it on the Oscar red carpet on Sunday night in a beautiful white gown. But it was her hair that drew the most attention from E! red carpet host Giuliana Rancic. The "Fashion Police" co-host commented on the "My Baby" singer's long dreadlocks on Monday night's Oscar edition of the show, saying, "I feel like she smells like patchouli oil and weed."

Zendaya responded immediately on Instagram, slamming Rancic for perpetuating what she said were "outrageously offensive" stereotypes. "There is a fine line between what is funny and disrespectful," Zendaya 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."

In addition to saying Rancic was stereotyping, Zendaya noted that her father, brother, best childhood friend and cousins all wear locs, as well as Ava DuVernay (director of the Oscar-nominated "Selma"), author Terry McMillan, Grammy nominated singer Ledisi, a number of prominent university professors and "many other men woman and children of all races."

What do they all have in common? "None of [them] smell of marijuana," she said. "There is already harsh criticism of African American hair in society without the help of ignorant people who choose to judge others based on the curl of their hair."

Z said she wore her hair in dreads at the Oscars to "remind people of color that our hair is good enough."

Rancic later apologized, tweeting, "I'm sorry I offended you and others. I was referring to a bohemian chic look. Had NOTHING to do with race and NEVER would!!!"

Lorde re-tweeted Zendaya's 'gram, and a number of other people also backed the Disney alum in light of Rancic's original comment.
