Golden gals gone wild! Joan Collins reportedly furious about raunchy scene in Shirley Jones' book

A battle is brewing between Joan Collins and Shirley Jones.

The former gal pals are reportedly in a heated argument over a particularly racy scene in Jones’ new book.

According to TMZ, Collins, 80, is fuming over a portion of “Shirley Jones: A Memoir,” in which Jones writes that her then-husband Jack Cassidy, Collins and Tony Newley nearly engaged in swinging.

Jones, 79, recounted in her book that after the two couples enjoyed dinner together, Newley suggested they all strip down and watch porn together.

"It was clear what Tony was leading up to – swinging," Jones writes, according to TMZ. The former “Partridge Family” star alleges she turned down the offer.

But Collins is adamant that the story never happened and, TMZ reports, she has sent Jones a cease and desist letter demanding the shockingly raunchy book be removed from bookstores.

Jones declined to comment on the situation. A reps for Collins did not immediately return FOX411’s request for comment.
