The 32-year-old, who raises two daughters with husband Cash Warren, said she was a wild child, reported Contactmusic.
"We accidentally drank Wild Turkey (whiskey). How old was I? 11?" Alba said.
To the confession, Alba's mother said, "It's a little shocking. You drank Wild Turkey in sixth grade?!"
"Do you remember when I used to steal the car and go to Jack in the Box? We would go and get food. That was our activity. I was 12," Alba added.
