Joan Rivers is reportedly on the verge of getting sued by none other than "Twilight's" Kristen Stewart whom she has accused of sleeping with her directors to get work in their movies. Joan Rivers has come up with a new book "Diary of a Mad Diva," which she claims to be a comic book. The "Fashion Police" star has bashed Kristen Stewart in the book and discussed her cheating scandal with Rupert Sanders.

"Many stars only do one thing well. Of course, the best one-trick-pony is Kristen Stewart, who got a whole career by being able to juggle a director's balls," Joan writes in the new book.

For readers who are not familiar with Kristen's cheating scandal here is the summary. The actress was accused of cheating on her then boyfriend and co-star Robert Pattinson with her "Snow White and the Huntsman" director Rupert Sanders. The pictures of the two kissing each other passionately were splattered all over the media and it also resulted in Sanders getting divorced from his longtime wife Liberty Ross.

Though the cheating scandal is true, Kristen did not take Joan's satire in a light mood and has threatened to sue her, TMZ is reporting. "I am now being sued by Kristen Stewart. She obviously didn't read our disclaimer, which says it's a comedy book," Joan revealed to the Web site.

The book is yet to be released in July and Joan has made it clear that she will not make any changes to the text related to Kristen Stewart. The passage will stay as it is.

"My answer to her was be glad you're not a Kardashian because they're mentioned a lot more in the book," Rivers told the Web site.

"I can't wait to get her into court because I'm gonna get a puppet and I want her to show me on the puppet where she thinks I claim she touched her director. I am looking forward to it," Joan told the Web site.

Joan's upcoming book is not only about Kristen Stewart's cheating but she is also aiming to make fun of a hoards of celebrities including Kim Kardashian, Miley Cyrus, Jennifer Lawrence, Taylor Swift and many more.
