Kelly Osbourne warned co-star Giuliana Rancic and the show Fashion Police that she would quit the show if they do not apologize for making a rather tactless comment referring to Zendaya's hair smelling like weed.

The 30-year-old host took to Twitter to air her disgust after Rancic quipped about Zendaya's hair at the Oscars red carpet, saying it smelled like "patchouli oil."

"I'm giving everyone involved 24 hours to make it right or the world will hear how I really feel," Osbourne posted on Twitter.

Osborne then made a follow up post, saying she does not 'condone racism,' thus, she was thinking of whether to stay or leave the show.

Zendaya tweeted on Monday night, saying that she felt Rancic's comments were "offensive" and "ignorant slurs."

"To say that an 18-year-old young woman with locks must smell of patchouli oil or 'weed' is not only a large stereotype but outrageously offensive," Zendaya posted on Twitter.

Zendaya's comments and defiance against Rancic's comments immediately gained the support of her fans.

"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," Rancic, meanwhile, commented.

Osbourne, meanwhile, has received negative feedback from netizens over her Twitter remarks. She remained unfazed, however, and tweeted: "I WILL NOT BE DRAGGED INTO THIS! The situation is being rectified like ADULTS by both parties. I hope you can leave it to them & do the same!

"You guys do realize that @Zendaya is my friend right?" she said in another tweet.

"I DID NOT MAKE THE WEED COMENT. I DO NOT CONDONE RACISM SO AS A RSULT OF THIS IM SEREIOULSY QUESTIONONIG STAYING ON THE SHOW! (Sic)"
