It looks like Kelly Osbourne has officially quit ‘Fashion Police’ as of Friday February 27 following controversy surrounding a joke regarding Zendaya Coleman last week as we previously told you.

Giuliana Rancic made the comment about Zendaya’s dreadlocks and how they looked like they smelled of “patchouli” or “weed,” and became the target of major scrutiny on social media. Osbourne later began to receive backlash although she did not tell the joke, as a result she threatened on Twitter to leave the show unless “the situation” was rectified.

“Kelly Osbourne is departing E!s Fashion Police to pursue other opportunities, and we would like to thank her for her many contributions to the series over the past five years, during which time the show became a hit with viewers,” E! Entertainment said in their official statement Friday.

Although Giuliana did issue a formal apology for her Zendaya comments, it appears there may be other reasons which prompted Kelly’s departure.

A source tells PEOPLE that Osbourne was frustrated about how little the network had been using her, especially during the awards season. “What’s funny is Kelly was fighting for airtime and wanted to talk on the Oscar show,” the source said. TMZ also reports that the tension started over the first episode the cast taped without Joan Rivers. Kelly was unhappy with the way the show was being produced. Producers,were “up to here” with Kelly so the handwriting was on the wall.

‘Fashion Police’ is said to return on Friday March 30 but there is no word on Kelly’s replacement.
