DAVID and Victoria Beckham are planning to add a fourth child to their family next year (08). The Spice Girl is desperate for a daughter and sister to three sons Brooklyn, Romeo and Cruz - and wants to time it so she can give birth after the band end their reunion tour in January 2008. The baby will also be born in Los Angeles - where David is playing for soccer team LA Galaxy. Victoria says, "We'd like to have another - maybe next year. He or she might be lucky enough to have dual nationality."
