The Times Square billboard of bare-butt Bethenny (“I’d rather go nude than wear fur!”) Frankel has the fur flying among her fellow “Real Housewives of New York City” stars. After Frankel blasted Jill Zarin for wearing fur, Zarin tweeted, “I wouldn’t throw stones at glass houses, my love.” Could she mean Bethenny’s new cookbook that’s full of chicken recipes? A source wondered, “How can someone who encourages people to buy and eat chicken be a pioneer against animal cruelty?” PETA’s Michael McGraw said: “Bethenny is not a vegan and never claimed to be. She has, however, brought much-needed attention to PETA’s anti-fur campaign.” After Frankel told us she was pregnant when the ad was shot and there was minimal airbrushing, ever-charming New Jersey housewife Teresa Giudice sniped, “Someone tell Bethenny that sperm does not make you look fat. I’m not buying the airbrushing thing in any case.”
