The pair are currently in New York supporting David's wife Victoria at New York Fashion Week, but it's not all been about catwalks and clothes.
David and Harper were spotted yesterday (10 September) enjoying some downtime in the warm autumnal sunshine.
After taking her to a children's playground, doting father David lifted his little girl into a swing before pushing her high into the air.
Dressed casually in a baker boy cap, T-shirt and jeans, the retired footballer blended into the crowd of parents.
Harper, meanwhile, looked super stylish in a pretty cotton dress teamed with funky Doc Martin boots. She was also sporting her fave topknot.
Once they had exhausted the swings, David couldn't resist a kick around - and a game of catch - with his daughter. But rather than play with a leather football, David gave in to a pink plastic ball!
The Beckhams spent most of the summer visiting friends in Los Angeles, before David, Victoria and Harper headed to NYC.
But in a recent interview, Victoria said: "The kids go to fantastic schools, they have lots of friends and our family live in London, we're very proud to be British."
