Is Katie Holmes a budding feminist? Holmes, currently filming “Mania Days,” was spotted dressed in all white, having dinner at Carbone in Greenwich Village on Tuesday with Gloria Steinem and two women. “Gloria and Katie were completely engaged in conversation,” says a spy. “They were hunched over the table to speak closer, even though they were sitting right next to each other.” We’re told the group stayed chatting for three hours. Coincidentally, Holmes and Steinem are from Toledo, Ohio.
