Jessica Alba wears Marc Jacobs as she graces the cover of Lucky magazine’s September 2011 issue, on newsstands Tuesday (August 9).

Here’s what the 30-year-old Spy Kids 4 and new-mama-to-be had to share:

On playing superheroes: “I pretended to be a superhero when I was a kid. I thought, if boys can do it, I can do it, I can do it better!”

On being strong-willed: “There’s a video of me when I’m three, saying ‘This is a woman’s world, and I don’t need a man for nothin’!’”

On her first big audition: “We all went out for it – my mom, my auntie, her four kids, my auntie’s boyfriend, my brother and I all sardined inside our Buick Regal. That’s how we rolled back then.” Once there, she was asked to list any acting experience. “I lied and said I done plays. My mom definitely taught me how to hustle.”
