Producers of “The Real Housewives of New York City” are desperately trying to recruit a new cast of beautiful, well-connected and wealthy women for the next season. Sources said the entire current cast — which includes Jill Zarin, LuAnn de Lesseps, Cindy Barshop, Ramona Singer, Sonja Morgan and Kelly Bensimon — could be axed, and after the success of the Beverly Hills version, Bravo chiefs want a new, glamorous crowd who move in celebrity circles. We’re told p.r. mavens Alison Brod, who has her own eponymous company, and Di Petroff, co-founder of Brandstyle Communications, have been repeatedly approached, but both have refused roles on the show. Brod said, “I have turned down every reality show offer — a pink office with 50 girls is a big draw for development people. That said, being on the finale of ‘The City’ and my name being called a c – – t on ‘Entourage’ [creator Doug Ellin named a character after her who sued Jeremy Piven‘s character Ari Gold for sexual harassment] was enough buzz.” Petroff declined to comment.
