Gwen Stefani and Gavin Rossdale PDA in Burbank Pictures

Gwen Stefani and Gavin Rossdale showed a little PDA yesterday, holding hands as they headed into a Burbank, CA, recording studio. Gwen's schedule has been hectic this Summer with the release of No Doubt's first album in more than 10 years around the corner. The singer has made several radio-station stops this month to promote the album, Push and Shove, and last week, Gwen and the band kicked off NFL season with a live, pregame performance in Rockefeller Center. Gwen also covers Marie Claire's October issue, showing off her rock-hard abs and talking career and family life in the magazine. The Stefani-Rossdales will have a lot to celebrate this month on both fronts: Gwen and Gavin mark their 10-year wedding anniversary on Friday, and Push and Shove will be released Sept. 25.
