What a happy boy!

Kenzo Lee Hounsou gets excited while sitting with Kimora Lee Simmons watching his big sisters Aoki and Ming play at Cross Creek Park in Malibu, Calif. on Sunday.

Later on, the 6-month-old got a lift from dad Djimon Hounsou (see extended post).

Aoki, 7, and Ming, 9 ½, are the model and reality star’s daughters with Russell Simmons.
