Seemingly always on the go, Gwen Stefani and Gavin Rossdale were spotted arriving at Heathrow Airport in London this morning (November 30) following an overnight flight from Los Angeles.

Joined by their adorable sons Kingston and 15-month-old Zuma, the rock royal couple are back in Gavin’s hometown after spending much of the summer in L.A.

Gwen was in good spirits considering she’s currently in the midst of a legal battle against owners of a Minnesota bar.

Along with Bon Jovi, the No Doubt frontwoman recently took legal action over accusations that the venue played their music without authorisation.

The pair are asking Sally’s Saloon and Eatery in Minneapolis, Minnesota to stop playing their music after allegations that the establishment lacked ownership of a proper music licence.

In the lawsuit, which was filed last month, both artists are seeking unspecified damages from the venue.
