The LA Galaxy star appeared on the Ellen DeGeneres Show last night and said they were both keen to have more kids.
'We're working on it,' David says.
'We're very family oriented. We always wanted a big family, which was weird because when we first got together we never even discussed how many children we wanted.
'We love kids so it's worked out perfect.'
David, 32, and Victoria, 34, have been married for almost 9 years. They have sons Brooklyn, 9, Romeo, 5, and Cruz, 3.
Earlier this week, David's dad Ted, 59, said they would like a daughter.
