Gwen Stefani and the gang know how to celebrate a good ol' fashioned holiday!

The singer was spotted with her boys Kingston, Zuma and hubby Gavin Rossdale in Malibu today as the family joined some friends for a fun barbecue in the sun!

The No Doubt frontwoman and family celebrated Kingston's 6th birthday on Saturday with a trip to Underwood Family Farms in Moorpark, CA. Looks like if you're one of Gwen's boys, the party never ends!
