With his much anticipated movie "Transformers: Revenge of the Fallen" coming to theaters in U.S. on June 24, Shia LaBeouf keeps generating media attention with his provocative talks about his family, telling Parade Magazine in an interview, "My humor came from seeing my parents have sex." That's not all, he admits that he also gets his sense of humor from smoking weed, seeing his mother being naked, and "just weird hippie stuff, twisted R-rated humor."

Aside from his sense of humor, Shia admits he is battling a few demons, just like some other famous actors. "They're all in pain. It's a profession of bottom-feeders and heartbroken people," he explains. "Most actors on most days don't think they're worthy. I have no idea where this insecurity comes from, but it's a God-sized hole. If I knew it, I'd fill it and I'd be on my way."

Shia goes on opening up about his feeling, "Sometimes I feel I'm living a meaningless life and I get frightened. I know I'm one of the luckiest dudes in America right now. I have a great house. My parents don't have to work. I've got money. I'm famous. But it could all change, man. It could go away. You never know."

He, moreover, also spills the beans on him becoming an alcohol addict that led to his DUI arrest back in July 2008. "Why am I an alcoholic? I haven't a ---- clue! What is life about? I don't know," he tells Parade Magazine's June 14 issue.
