Gwen Stefani and husband Gavin Rossdale with son KingstonGwen Stefani’s spokeperson has denied rumours that the No Doubt star is pregnant with her second child.

Gwen has made no secret of her desire to expand her family after giving birth to son Kingston in May 2006 but after rumours started circulating last week, her spokesperson told Us Weekly magazine: “She’s not pregnant.”

A source close to the star went on to explain though: “They are trying. Trying very hard. They love Kingston so much and they think it would be great if he had a little brother or sister before he gets too much older.”
