Gwen Stefani spent Saturday afternoon running around LA with sons Zuma and Kingston Rossdale. The trio went shopping then later stopped by a park and snacked on Popsicles. Gavin Rossdale couldn't join them for the playdate as he's currently touring through Europe with Bush. The band is on the road through mid-September, then heads back to the States for additional gigs.
Gavin's return home comes just in time for Gwen's next major performance. No Doubt will open the iHeartRadio music festival on Sept. 21. They've been selected to kick off the celebration on Friday and will be followed throughout the weekend by other industry hit makers like Rihanna, Green Day, Taylor Swift, Pink, Usher, and Shakira.
