OLIVIA MUNN DISCUSSES VERBALLY ABUSIVE STEPDAD: Olivia Munn didn’t have a picture perfect childhood. The actress discussed her verbally abusive stepfather in a new interview with Ocean Drive magazine, describing him as “the Devil.” She explained, “He would always say, ‘You’re not smart enough, pretty enough, you have no talent,’ and it would knock me down, but it wouldn’t keep me down. When [my stepfather] would be screaming his head off in the living room, I would hustle everybody into my room and launch into imitations of teachers or do scenes from movies. And that would take their minds off of the hell that was happening down the hall.”
