'Fashion Police' star Kathy Griffin is leaving E!’s hit show after seven episodes, the network announced Thursday. The 54-year-old had signed on to host the show following Joan Rivers’ death in September.

In a post on her Twitter account, Griffin spoke out about what prompted her decision to leave the show.

“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 on,” Griffin wrote. "I wish E! and the E! team only the best and I hope to continue to make you all laugh performing live or on television where I can be smart, irreverent, unrepentant and unafraid in an observational way that is candid, honest and justified. Thank you to my fans for taking this ride with me."

The news of Griffin’s exit comes days after Kelly Osbourne's announcement to leave the show over racially insensitive comments made by co-host Giuliana Rancic. Osbourne reportedly served as the show’s co-host for five years. A TMZ report last week claimed that Griffin wanted the final say over who would succeed Osbourne on the show.

"We can confirm that Kathy Griffin is leaving E!'s Fashion Police," the network said, in a statement Thursday, according to E! News. "We wish her all the best and are grateful for her time on the show, as well as the many laughs that she gave us all. Fashion Police will return, as scheduled, on Monday, March 30, at 9 p.m. with our talented co-hosts Giuliana Rancic and Brad Goreski, and executive producer Melissa Rivers.”
