Ramona Singer has fired a warning shot at her former Real Housewives of New York co-star Jill Zarin, warning her to stay out of her “personal business” and stop taking about her divorce.

Singer and her estranged husband Mario Singer announced their separation after they got into a domestic dispute at their shared Hamptons home, where she caught the love rat with rumored gal-pal, socialite Kasey Dexter.
