(Cover) - EN Showbiz - Gwen Stefani says criticism is "like water off a duck's back".

The No Doubt singer refuses to get upset over rumours and gossip about her private life or career. She remains confident and focused on the truth.

"That someone would say something untrue or bad about me doesn't bother me," Gwen told the September issue of Harpers Bazaar magazine. "It's like water off a duck's back."

Gwen describes herself as a "passive" person. She doesn't let things faze her and reveals this is a characteristic she was born with.

"There's something in me, being this passive person, that those kinds of things don't upset me. I know they can say anything; they can just make something up," Gwen continued. "I've always been passive. I was never a rebel... My mom calls me a peacemaker. I want everyone to be happy."

The blonde singer balances her laidback side with her outrageous performing persona. She enjoys creating drama on stage.

"But I have a super big opinion on everything artistic that I do. I know what I like and I know what I hate - that part of me isn't passive," the feisty star added. (C) Cover Media
