ABC Family said Thursday the comedy-drama pilot, titled "The Fosters," is about two women raising a "21st century," multi-ethnic mix of foster and biological kids.
Lopez will be an executive producer for the hour-long project. Casting was not announced.
Her company, Nuyorican, is in development on other TV series, including "Taming Ben Taylor," a romantic comedy starring the actress-singer, and "Sweet Little 15," a Mexican girl's coming-of-age story.
Lopez, who recently exited "American Idol" as a judge, also is developing films through her company.
