Gwen Stefani headed to a park with Kingston and Zuma in LA yesterday. Kingston and Zuma seemed to be enjoying the afternoon sunshine since they took their shirts off for the outing, and Gwen also made sure her oldest had plenty of sunscreen on his face. Gwen and her husband, Gavin Rossdale, had an adults only night out on Thursday when they checked out the opening of Art in the Streets at MOCA. A redheaded Drew Barrymore was also on hand for the event, which happened just ahead of the release of Scream 4. Drew Barrymore was featured in the first Scream movie trailer, but her character didn't last long enough to make it into the sequel.
