London: Singer Gwen Stefani and her husband Gavin Rossdale say they don't want to find out the sex of their baby before the birth.

Contactmusic.com reports that the couple want to know the baby's sex only when she goes into labour, just as she did with her elder son Kingston in 2006.

Rossdale appeared on the radio show with Ryan Seacrest as the DJ and said, "We don't know the baby's sex. It was a surprise last time so, we're kind of working on that this time."
