Gwen Stefani was all covered up for a visit to the beach in Malibu yesterday with her husband, Gavin Rossdale, and their sons, Kingston and Zuma. Both boys ventured into the water, while Gwen and Gavin managed to fit in some PDA. The foursome enjoyed their latest outdoor adventure after a weekend full of wagon rides and visiting family. Gwen and Gavin have both been able to spend the last few weeks close to home, after his touring with Bush took their clan to Chicago in June.
