Crappy actress Kristen Stewart threatens to sue old comedienne Joan Rivers

Kristen Stewart probably won't be waiting in line to purchase a copy of Joan Rivers' new book, "Diary of a Mad Diva."

Stewart reportedly moved to take legal action against Rivers over a passage in the comedian's book about the actress' affair with "Snow White and the Huntsman" director Rupert Sanders. In her book, which is due out next month, Rivers wrote: "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."

"I am now being sued by Kristen Stewart," Rivers told a TMZ cameraman. "She obviously didn't read our disclaimer, which says it's a comedy book. 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."
