'Fashion Police' Kathy Griffin, Giuliana Rancic Feud: Kelly Osbourne's Co-Star Won't Talk to E! Host Ever Again Following Cancellation

It seems like all hell has broken loose on Fashion Police. The panelists have been at each other's throats since Giuliana Rancic uttered the now-infamous diss about Zendaya Coleman's dreadlocks. Not only did Kelly Obsourne up and leave the show over the controversy, but now it seems Joan River's replacement Kathy Griffin has also handed in her notice. Not only that, but should the show get canceled, it seems that none of the stars will be parting ways on good terms with each other.

According to Radar Online, it seems Kathy and Giuliana are definitely not going to be amicable should they have to say farewell to the show.

"Kathy is done with the drama and she is done with Giuliana," an insider explained to the site. "Kathy has not spoken to Giuliana and she has no intentions of ever speaking to her again, unless she has to."

It seems it was Rancic trying to throw Kathy under the bus for the Zendaya comment that really put a wedge in their relationship.

"Giuliana tried blaming Kathy and said that it was actually her fault, but later changed her tune to say it was the writer's fault," the source explained. "Kathy did not appreciate being blamed and Giuliana showed her true colors by trying to throw her under the bus."

While Giuliana did apologize for her comments it seems Kathy has already moved on from the show and is thinking about other projects, even taking to her Twitter account to address her leaving the series.

"After 7 episodes of Fashion Police, I discovered that my style does not fit with the creative direction of the show & now it's time to move," the star wrote in a lengthy message.

"Kathy's words on Twitter are the last that she wants to discuss this," an insider explained to Radar. "She has already moved on."
