Gwen Stefani takes a relaxed approach to tabloid speculation about her love life, insisting false reports about trouble in her marriage to Gavin Rossdale are like "water off a duck's back."

The No Doubt frontwoman has long been dogged by rumours she is on the verge of splitting from her husband, but the singer admits she would rather get on with her life than worry about the headlines.

She tells Harper's Bazaar magazine, "That someone would say something untrue or bad about me doesn't bother me. It's like water off a duck's back. None of that stuff matters. 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. But what are you going to do? It's not part of my reality, so it's OK."

Stefani and Rossdale, who married in 2002, are parents to sons Kingston, six, and Zuma, who turns four on Aug. 20.
