Gotta love a good celebrity feud. 

Brooklyn native Rosie Perez released some scandalous secrets about Jenny From the Block. 

In Perez's tell-all memoir, Handbook for an Unpredictable Life, the actress opens up about her on-going feud with Bronx native Jennifer Lopez.

The New York Post pulled out several excerpt form the book where she recalls her days on In Living Color with Lopez. 

Making her debut in September 1991, the future pop diva didn't immediately connect with her fellow dancers. 

"All of the girls were coming into my office complaining how she was manipulating wardrobe, makeup and me, all to her advantage … [Later, she went off on me] some ghetto biotech, screaming and pounding her chest! … [She said] '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. tearing me like Sh*t! I know i'm good! I'm bette than any of these girls and you know it." 

Rosie claims that as JLo's star rose, her ego did, too, as well as the chip on her shoulder.

"I was blindsided [when she ignored me]. I thought we were cool. I called her up. She wouldn't pick up. Frustrated, i left her an irate message on her answering machine. instead of calling me back and hazing it out like friends do, she went on a major talk show and reiterated my lashing… [Months later] Jennifer came over to be [at a club], smiling, saying hello as if nothing happened. I should've let it go, played it off, too. Instead, I killed her with biting tongue."
