"She's great," the soccer player said of his youngest child, 14 months. "She's been running around for a few months now, so we're all chasing her and catching her when she falls. It's great to have another lady in the house." (David and fashion designer Victoria Beckham, 38, are also parents to sons Brooklyn, 13, Romeo, 10, and Cruz, 7.)

According to David, his daughter is "a good mix" of both parents. "She kicks a ball around," he told Us, "but she also carries handbags."

As for his sons? "It would be easy for our kids to sit back and not work for anything, but they're not like that," David told Men's Health in March. "They're as competitive as Victoria and me."

David added, "We're very lucky with our boys: They want to win. They want to work at something. They know their values. That's the way we've brought them up so far, and that's the way we'll continue to bring them up."
