Real-life Ramona is so unhappy about her on-screen portrayal that she's suing for defamation.
Samantha Barbash sued STX, Gloria Sanchez productions and JLo's Nuyorican Productions.
Barbash says the filmmakers exploited her likeness without permission and defamed her.
She says the depiction is libelous per se because it involves the commission of a crime.
Barbash is seeking at least $40 million in damages.
She is asking the court for an in junction banning distribution of the film.
She is ordering defendants to give her all copies of the material.
