Hi, Jennie. Hi. Great to see you again. Thank you. How are those girls? I can't believe now the oldest is 16 years old. I know. I can't believe it either. 16, 11 and 7. My little birdies. Tell everyone their names. Luca Bella, Lola Rae and Fiona eve. How is that four gal, one house, probably a lot of carpooling. We have so much fun. I mean, we are -- it's like a party all the time. A lot of nail painting. Really. Preteens and teenager girl, party all the time. That gives me hope. Spend a lot of time doing homework. Their schedules are like packed and I do a lot of coordinating. Tell me why you decided now is the right time to write a memoir. I couldn't -- you know, it wasn't I hadn't done and wanted to take the challenge and it scared moo he to death. I had never written and it was sort of an artist lick outlet for me. You're so open and honest in the book. You talk about your split from your now ex-husband. You talk about your dad's passing. Hard for you to let go or cathartic? In some ways cathartic and very eye opening for myself in a good way to sort of take a look and see how my life has progressed and all the things that have happened and how they've molded me into the person that I am today. We've heard from so many of our viewers who just absolutely adored you on "90210." 1990 you joined the cast. I didn't realize until I was Reading that you started in beauty pageants and plucked out of Arizona. Yeah. And hired almost right away on to such an iconic show. What was it like growing up on the set of "90210"? It was -- we spent ten years in a cave basically and that was our high school and our college and we had a great time. I mean, what an experience. I wouldn't have traded it for the world but in some ways I missed out on a lot of things but in some ways I was very lucky so it was like, you know, how do you -- Hardest part for you working on "90210," what was the toughest. I think the toughest were the hours giving up your life in that way, you know, 16 to 18 hours every day working like an adult at age 16. Yeah. Everybody wants to -- I think would like to believe you guys all still keep in touch and you said, we do. We do. Some of us really are like brothers and sisters and we're always there for each other and very close, yeah. Brother Luke Perry or -- No, yes, brother. Well, yes. That was fun last year. You were on "Good afternoon America." You were in an ad together and speculation ran wi. Why do you think people got so excited that even the idea that you guys might be a couple? It's just Kelly and Dylan, I don't know, people just have this image this their mind of what, you know -- I don't know. It was pretty surprising. It is but that our fans are so loyal from ha show and we're so grateful for that. What a great fan base and they've gone with us to all of our other jobs, all of us so it's so nice. I'm glad you mentioned other jobs. Now you'll work with your pal Tory. Tell us about that. We are doing a show for ABC family, "Mystery girls" and she and I are so thrilled to be working together. Executive producing it and having the best time on cam are and off camera and can't wait to get started in April. I want to hear about the title of the book. Why did you guidecide to go with "Deep thoughts from a Hollywood bond." Maybe you've been teased a time or two. I have a lot going on in here. There's a lot of stuff going on and I wanted the book to be reflective of my internal conversations with myself and wanted to share with other women, other people. You're also sharing you are he a photographer and I didn't realize we share a common bond in design and you're doing a show where you're renovating your own house. I am. I am building a house for HDTV and for my girls and myself to live in and it's quite a project. And single parenting. How do you do it all? A calendar with a lot of things on it. A lot of scheduling. Have you started it? Can you tell us about it. We are all -- we put in windows this week so very exciting. Give me an idea on style. What's your -- I'm going modern. I have never done -- this is my first modern house and it's a learning curve. Yeah. All right. So again the tight many of the book "Deep thoughts from a Hollywood blond." What's the one -- "Good morning America," what's the one misconception you wanted to get out. Oh, geez. In the book. Enough is muff. The one misconception? Give us one example. We're bad drivers. I think that's a good one. I think women in general we're not bad driver there is no. So Jennie, you can drive very well. You can build houses. You can write.
