Gwen Stefani & Her London Lads

Gwen Stefani and husband Gavin Rossdale were spotted out and about with their two sons - Kingston, 3 1/2, and Zuma, 15 months - in London on Sunday (December 6).

Gavin recently said that they are celebrating the festive season in England.

We alternate each year. Last year we stayed in the Los Angeles area, but now we're excited about having an old-fashioned, European holiday."
