LONDON: Gwen Stefani — who has sons Kingston, three, and one-year-old Zuma with husband Gavin Rossdale — claims the only reason she has never gone off the rails is because she is so worried about what her parents would say. The 39-year-old singer said, “I was thinking today, ‘How am I going to make sure that Kingston never does anything bad and doesn’t get arrested? How did I stay out of trouble?’ And I know it’s just because my parents are so strict. I mean, I’m still scared of them!” Gwen says being a mother is the most important part of her life, but is aware her children’s upbringing is totally different from her own. She told Glamour magazine, “I grew up in a normal family. The other evening, at the end of the night, “The hardest thing I’ve ever done is have kids! But, of course, the rewards are great.”
