"The New York times" best-selling author Carole radziwill star of "Real housewives of New York City" knows a thing or two about ga dating. In this chip she talks about her greatest breakup. You read about famous couples and break up and they're all like we love each other but going our separate ways. Yeah. It's all like Jen and brad hugging on the beach and three months later they're getting divorced. Is that how it was for you. Not how it was at all. So she puts her romantic experience to expert use in a new novel called "The widow's guide to sex and dating". And Carole radziwill is joining us now. Welcome to "Good morning America." Thank you. Great to see you again. Thank you. Your first book very different than this. What remains is your memoir based on the death of your husband and now you move to fiction. Yeah. Which was easier? You know, when I was writing the memoir, I thought it would be so much easier to write fiction because you could make it up but actually fiction is a lot harder because you're only limited by your imagination so that's daunting and you can always second-guess yourself, I can make this better, more interesting but I loved doing it and, you know, I loved creating the characters and so it was -- I have to tell you I just kept dipping back and forth. Knowing a little bit I kept thinking, is this fiction or is this not? Are these just -- No, you know, it really is fiction obviously. I was a young widow and people identify Clair with me and that's great. I think I'm a little bit of all of the cashes but most writers write about what they know and your observations and experiences but also your imagination. It's juicy. It's definitely you got a little flavor. "Real housewives" flavor and men and of all she dates one got my wheels churning. Which one? Movie star named jack sounded an awful lot like someone you dated last name rhymes with George Clooney. How close to reality? It's, you know -- I was trying to create a character that all women would fantasize about and jack Huxley is a charismatic, charming, handsome very complicated character and when -- Any scoop, any Intel? When you're creating any kind of character like that there will always be a little George Clooney in there whether you kissed him or not. Well, you have. We're not worthy. In the Eisenhower administration it was so long ago but, yeah. It's a great read and I know very busy with the "Housewives" in the next episode you have an episode. I scream and I think the audience will see a different side of me. One women maybes a ridiculous accusation, a kind of scandalous about my career and colleague -- Who is that? That I respect. Have deep respect for and, yeah, sometimes you got to hit crazy with crazy and, you know, you grin and bear it and you rely on the audience to figure out, you know, why she's saying exactly what she does and I think she maybes it pretty easy. Because you don't use your voice at that level very often it's very effective. We know you're not kidding around. No, no, I think it was very real emotion, probably the most real emotion you'll see on reality. It was like, you know, it was like taking a bullet so I was not -- I was not happy. Fighting fire with pyre. Crazy with crazy. Carole radziwill, the book is really fun, congratulations. Thank you so much. It is called "The widow's guide to sex and dating" and it is in stores right now.
