Singer Gwen Stefani and hubby Gavin Rossdale have cancelled their plans for more children, so they can catch up on all their lost sleep. The happy pair already have two sons, 2-year-old Kingston and 7-month-old Zuma. Rossdale is admitting he and Stefani would love to try for a little daughter, but they are too tired to think about another child right now. He says, "Well that would seem logical, but then again, so would sleep! A bit of selfish time would be nice."
