Actress Jessica Alba hated growing up as a teenager - because she was 'too mature' for her age. The 26-year-old Fantastic Four star struggled as a young actress, and insists she would love to erase the bad memories of her childhood. She says, "I would omit my teens (if I could). They were really tough. I was always a grown-up in a child's body, in my mind - incredibly opinionated, stubborn, strong-willed, very independent. I'm on videotape when I was three talking about being an independent woman! "Then when I was a teenager it was a little bit paralysing because I felt I was an adult but I didn't have any right as an adult."
