Angelina Jolie says that she wasn't kidding when she flaunted her torrid marriage to Billy Bob Thornton -- the his-and-hers tattoos and vials of blood, the boasting about their sex life -- even though she says they're no longer friends. In an interview with Barbara Walters, which ABC will air on ''20/20'' on Friday, Jolie says of her ex-husband, ''I thought he was amazing. And now I just feel like I don't know him.'' Their two-year marriage soured in 2002, shortly after they adopted a Cambodian orphan, Maddox. ''It's like we just changed,'' she says. ''We became very different people, and I wouldn't know what to talk to him about.''
Jolie, whose ''Lara Croft Tomb Raider: The Cradle of Life'' opens July 25, says she's similarly estranged from her dad, Jon Voight, despite their brief reunion playing father and daughter while shooting the first ''Tomb Raider'' in 2000. ''It was a hello and goodbye. And that was kind of that time for us,'' she tells Walters.
Jolie says she's so devoted to Maddox that she plans to raise him in Cambodia so that he'll know his heritage. ''I think I'll never get married again,'' she says. ''I don't want to have a temporary father for my son.'' She adds, ''I don't really know if I'm meant for marriage.''
Still, she says, ''I consider myself a very sexual person,'' says Jolie. "If I fell in love with a woman tomorrow …it's right to want to kiss her and touch her.'' In fact, she said, she had a bisexual relationship when she was a teen, one that involved ritual self-mutilation. ''I got knives out and had a night where we attacked each other... it felt so primitive and it felt so honest... and then I had to deal with, you know, not telling my mother, hiding things, wearing gauze bandages to high school.'' She says, however, that she's left those days behind. ''I think when you make a decision to have a child, you cannot think about suicide again and you can't be self-destructive.''
