The Rossdale boys left mom and dad at home for a fun trip to the park with grandpa.

Kingston and his little brother Zuma enjoyed their quality time with Gwen's pop at Castle Park in Sherman Oaks. These little cuties are so darn stylish! Love Kingston's knee high socks.

Gavin and Gwen's little boy is certainly a chick magnet. See him putting the squeeze on a cutie at the park ... after the jump.
