Gwen And Her Boys Get A Jump On Halloween

Gwen Stefani is getting her boys ready for fall a little early ... by Halloween costume shopping in August!

The No Doubt rocker took Zuma and Kingston to a local costume store where they each picked out a new look - Kingston, a cowboy; and Zuma, Batman.

Then, after a tough morning of shopping, they headed the the park to cool off in the fountains!
