Revealing a cache of scandals and secrets in her new memoir, Rosie Perez had some bitter things to say about long-time nemesis, Jennifer Lopez.

Perez's "Handbook for an Unpredictable Life" details how she met "Jenny from the Block" in 1991 for "Living Color's" open casting call for the show's Fly Girl dancers, which Perez choreographed.

The 49-year-old stated that she convinced Keenan Ivory Wayans, host and creator of "Living Color," to sign on a "chubby and corny" Lopez, thereby giving her a shot at fame.

However, Perez wrote that trouble began when Jennifer didn't get along with her dance companions, writing that, "All of the girls were coming into my office complaining how she was manipulating wardrobe, makeup, and me, all to her advantage," adding that Lopez got rid of her "sweet girl act" and "went off" on Perez like "some ghetto biatch, screaming and pounding her chest."

Rosie Perez even alleged that Jennifer shouted at her, "You pick on me, me and only me, every f**king day! Every f**king day! I work my ass off, deliver and you keep pushing me aside, treating me like s**t! I know I’m good! I’m better than any of these girls, and you know it."

Finally, Perez claimed that, after the "Back Up Plan" starlet left "Living Color," she cut Perez with "disparaging comments", only to later meet her again at a night club years later, acting as if the two were the best of friends.

About the encounter, she wrote, "Jennifer came over to me, smiling, saying hello as if nothing had happened. I should’ve let it go, played it off, too. Instead, I killed her with my biting tongue."
