Kelly is responding to the firestorm Giuliana sparked with a comment about the Disney star's Oscar look -- which included new dreadlocks. Rancic said she thought Zendaya must smell like patchouli oil or weed. Kathy Griffin joined in on the "weed" comment.

Kelly went off on a Twitter rant, saying ... "I'm giving everyone involved 24 hours to make it right or the world will hear how I really feel." She added she doesn't condone racism and is seriously questioning staying on the show.

Osbourne reminded fans she's friends with Zendaya -- who herself blasted Rancic for making such an "outrageously offensive" stereotypical comment.

It sounds like no one involved is buying Giuliana's claim her remarks "had NOTHING to do with race." update_graphic_red_bar4:30 PM PT-- Looks like Kelly has pull ... Giuliana just apologized again -- this time on the air during "E! News."
