Gwen Stefani and Gavin Rossdale spent yesterday afternoon chilling outside in Palm Springs, CA with their boys Zuma and Kingston. Zuma tried to keep cool in the hot sun by just wearing his diaper and a little t-shirt. The Stefani-Rossdales make visiting the resort town an annual tradition, timed to coincide with the Indian Wells Tennis Tournament. Gwen and Gavin were in the stands Tuesday to cheer on their friend Roger Federer — that is, when they weren't otherwise occupied with kissing and hugging.
