Gavin Rossdales son Kingston Rossdale is the World’s Greatest Smile Hunter

Gavin Rossdale and his wife Gwen Stefani get in some family bonding time Sunday afternoon with their 2-year-old son Kingston.

The happy family was seen at a park near their home on Mulholland. Gwen wore shoes from her own fashion line again — KATELLA II in white/midnight.

Kingston’s cute t-shirt reads: “World’s Greatest Smile Hunter — Go For It!”
