Former “Murphy Brown” star Candice Bergen won’t be humoring any haters, if her new memoir “A Fine Romance” is any indication. “Let me just come right out and say it: I am fat,” Bergen writes in the new book, excerpted by Page Six. “In the past 15 years … I have put on 30 pounds. I live to eat. None of this ‘eat to live’ stuff for me. I am a champion eater. No carb is safe — no fat, either.” Champion eater, you say? I’ll buy it when I see you sporting an eating contest trophy or two, but until then I’m glad you’re enjoying yourself. Follow Ned Ehrbar on Twitter: @nedrick
