Jennifer Lopez has butted heads with fellow American Idol judges over the years. But that's nothing compared to the apparent feud she's had with a co-star from a different project. 

Actress Rosie Perez's new memoir, Handbook for an Unpredictable Life, hits stores later this month. In the book, Rosie slams Jennifer Lopez, whom Rosie worked with on the hit '90s sketch show, In Living Color. 

Rosie, 49, was working as a choreographer on In Living Color when J-Lo auditioned for a role as a Fly Girl. Rosie was immediately impressed by her, saying she thought Jen was beautiful and convinced the producers to hire her.

However, Rosie says that, after Jennifer got hired, the show's other dancers immediately complained about her bad attitude. "All of the girls were coming into my office complaining how she was manipulating wardrobe, makeup, and me, all to her advantage," Rosie says. Rosie says Jen felt that the other dancers were "jealous."

Eventually, Rosie says that Jennifer "went off" on her like "some ghetto biatch, screaming and pounding her chest!" Rosie says that Jennifer screamed 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." Wow.

Jennifer left the show after two years to pursue an acting career. Rosie says that J-Lo approached her at a nightclub years later and pretended as though things were all good between them, but Rosie wasn't having it. "I killed her with my biting tongue," Rosie quips about their exchange.

Rosie — who appeared on several episodes of In Living Color as well — broke out as an actress in the late '80s and early '90s with such films as Do the Right Thing, White Men Can't Jump, and the Nicolas Cage rom-com It Could Happen to You. She has been in such recent films as Pineapple Express and last year's star-studded drug drama, The Counselor.

But we're guessing she won't co-star with J-Lo in anything in the near future.

What do you think about Rosie's claims?
