This may not go well with Kristen Stewart's fans. In her new book titled "Diary of a Mad Diva," Joan Rivers has dissed Stewart by claiming that the former has slept around with directors to ride her way to the stardom.
Rivers is known for her harsh criticism on the celebrities and this time the "Twilight" starlet has come under her radar.
Rivers took shots at Stewart for her alleged affair with the "Snow White and the Hunstman" director Rupert Sanders.
"Many stars only do one thing well," Rivers wrote in her book. "Of course, the best one-trick pony is Kristen Stewart, who got a whole career by being able to juggle directors' balls," reported Page Six.
Rivers not only said harsh things about Stewart but she also criticized the risqué fashion sense of the female stars at the public events.
"No one is allowed to dress up anymore during Award Season...The networks have new decency guidelines, which insist that no more breasts, buttocks or genitalia show. Luckily, because of celebrities like Pharrell and his stupid hat, we'll still be able to see a–holes," she continued in her book.
Rivers even dissed the widespread use of Vampire theme in the entertainment industry and suggested that the world is done with them and if she wants her life to be sucked out of her, then she would rather spend time with Bethenny Frankel.
"They're everywhere: movies, TV, museums. Enough already! If I want the life sucked out of me, I'll spend a long weekend with Bethenny Frankel," she wrote.
River did not stop here and had some vicious things to say about Paris Hilton.
"It's all over the news that Angelina Jolie had a double mastectomy to prevent getting cancer. I think Paris Hilton should...step up to the plate and try to prevent STDs. It would be so easy for her. All she would have to do is have her knees fused together," she further wrote in her book.
Rivers is understood to have beef with most of the celebs in the industry. Much recently Kim Kardashian was requested to be seated away from Rivers at NBC cable upfronts in New York on 15 May.
"Khloe and Kim were seated next to Joan Rivers, but they had them move her," a source dished to US Weekly. "The 80-year-old recently made fun of Kim and Kanye West's daughter, North West, even going as far as to call the 11-month-old 'ugly'."
"Kim and Khloe both don't want drama and can't fake it anymore with Joan, so they asked the staff to keep them separate," the source said further
Stewart is yet to give any reaction on Rivers' cruel diss.
