Our american sweetheart is back. Wearing hearts at the golden globe this weekend. Good evening. Pregnant with her second child. Yes, I am writing a heart next to my name. And a in uh book, drew barrymore is ready for her next act. I love the very exposed, humorous, imperfect, never trying to tre tend to be perfect journey that I've been on in my life. That journey has been turbulent and often very public. E.T. Phone home. Steven spielberg's "e.T." Catapulted drew barrymore to international stardom. Your movie is up for an academy award. What do you think about it? I don't know if we will win, but I'm hoping so much. Then a crash that so many child stars have taken since, but at the time was shocking. By 13, barrymore had been to rehab for alcohol and drug abuse and written a best seller about it. And she attempted suicide and later became emancipated from her parents. And by 19, publicly explored her sexuality in "interview" magazine posed for "playboy," and got her first divorce. Is there anything you look back at and you just kind of cringe? No. And I celebrate that I had any sense of freedoms at a certain point because I don't feel like that now. Reporter: These days she's a proclaimed actor and director. Her demon and bad girl reputation, a lifetime ago. That person seems like a beautiful, distant, unattainable memory. And I know it's still me and I'm so glad that it was, because it was such a fun part of the steppingstones. And I never have to worry that, like, I didn't get anything out of my system. Barrymore's latest role is mom. She and her husband, an art consultant, are expecting their second daughter. So you're six months pregnant. Yes. And your little one is about a year and a half. I will never complain for as long as I live, because I know how blessed you are to even make babies. I can't believe I get to make healthy babies. I could cry talking about it. So I'm just like, here we go. Reporter: But in an age when everyone's past is a click away -- will you tell your kids about the good, the bad and the ugly? The best kind of parent you can be is to lead by example. And whatever I've experienced in my life is a part of my story, and I'm proud of this. But it's someone who wakes up early, works all day, believes in charitable work, business minded, diligent, accountable, problem solving. Very different childhood from the one she had. I'm so much about school and consistency and tradition. Reporter: What do you think that comes from? I have no idea. I don't know where my business sense comes from. My parents were hippies. Reporter: That work ethic and business acumen have helped create a business empire. She has a production company, flower films, making hits l and "50 first dates." Are you okay? Isle be right back. Hey, come here! I think he's had enough. Reporter: There's barrymore wines, a line of makeup, flower beauty, and now a new book that's close to her heart. Photography calms me and it stops me and it wows me. Reporter: Barrymore released "find it in everything" a collection of photographs of heart shapes that she's spotted and snapped over the past 20 years. I loved this shape so much, i would see it in a fragment of light, I would see it in I fur of my dog. It would suddenly unexpectedly have something heart shaped about it and it made me happy. This was the most wopdnderful afternoon. That's charlotte gainsburg. She's so cool. I felt like such a nerd shooting her because she's so cool. Reporter: She gave "nightline" an exclusive first look at her portfolio and of her personal pictures. Your human eyes don't see this. They don't capture the world like this, but photograph y does. I love moments like that. Reporter: When you look at your work, do you say, I have real talent? No. But if you would ever think i do, I'm stumped. I was like -- Reporter: What does this mom and aspiring role model say when she looks back at her "playboy" moods? I have no regrets at all. I'm just in a different mind frame. I'm in mom mode now. I can't even think about it. What if your daughter comes to you at 18 or 19 and says mom, I would to pose in "playboy." I would not let her. I would influence her not to because my life choices are not supposed to be the gateway to somebody else's. That's my journey. Reporter: A journey with no apologies.
