Seemingly always on the go, Gwen Stefani and Gavin Rossdale were spotted arriving at LAX Airport to catch a flight out of Los Angeles on Sunday afternoon (November 29).

The No Doubt frontwoman and her Bush rocker hubby dutifully tended to their young sons, Kingston and Zuma, loading them into a double stroller before heading into the terminal entrance.

The family flight comes shortly after Gwen announced on her Web site that she's expanding her L.A.M.B. and Harajuku Lovers business endeavors with a new collection of accessories designed for Apple products.

She tells, "The collection includes everything from iPhone clutches to computer bags and is available online now. In the upcoming weeks, look for the new L.A.M.B and Harajuku Lovers collection for Apple at Macy's and Bloomingdale's."
