And the gloves are off…
Rosie Perez documents her longstanding feud with Jennifer Lopez in her upcoming memoir, Handbook for an Unpredictable Life: How I Survived Sister Renata and My Crazy Mother and Still Came Out Smiling (With Great Hair).
The two Puerto Rican actresses first met on the set of In Living Color back in 1991.
Perez was the show's choreographer at the time and recalled how Keenan Ivory Wayans called J.Lo "chubby and corny."
She explained how Kenan, the hit series' creator, demanded that Bronx-born Lopez cut her hair and drop a whopping 20 pounds before becoming a Fly Girl.
And despite being labeled a diva by the other dancers, Perez initially shrugged off the rumors and thought they were all just "jealous."
But things quickly changed when the American Idol judge ditched her "sweet-girl act" and "went off" on Perez.
She detailed how J.Lo turned into "some ghetto biatch, screaming and pounding her chest." Oh the drama!
Lopez apparently had a bone to pick with Perez and made "disparaging comments" about her former choreographer after leaving the show.
"I was blindsided," Perez wrote in her book.
"I'd 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 hashing it out like friends do, she went on a major talk show and reiterated my lashing."
But Perez doesn't want the years-long feud to overshadow her professional success.
"We ladies of color all know how hard it is for us in the entertainment business," she wrote in the book.
"This kind of s--t hurts us all and those that follow in our footsteps."
