. "Let's see what happens. Maybe I'm just a late bloomer."
But on a serious note, the platinum-haired singer says it's just not in her nature or upbringing to get into trouble – despite her over-the-top stage persona.
"I was thinking today when I was driving, 'How am I going to make sure that [my son] Kingston never does anything bad and doesn't get arrested?' I was thinking, 'How did I stay out of trouble?' And I know it's just 'cause my parents are so strict," she says. "I mean, I'm still scared of them."
As for the way her husband – musician Gavin Rossdale – handles parenthood, Stefani has nothing but kudos.
"I always thought he'd be a good dad," she says. "And he has basically lived up to that and beyond, beyond. He's very, very passionate, and he's very intense. He's made to be a dad. I'm very lucky."
