Is Jill Zarin grooming a new crop of reality stars? Sources say the “Real Housewives of New York City” loudmouth has recruited three young bloggers who signed 30-page talent contracts making Zarin their agent so she can pitch them exclusively to networks like Bravo, Oxygen and Logo. Zarin, who works with hubby Bobby in the fabric business, “considers herself to be a Jewish Benny Medina,” who famously managed J.Lo, a source says. But Zarin’s rep denies she’s running a talent agency.
