Gwen Stefani & Gavin Rossdale: We Are The Titans!

Gwen Stefani and husband Gavin Rossdale stay bundled up as they enjoy a walk in the park with their sons Kingston, 3, and Zuma, 15 months, in London on Sunday (December 20).

The jet-setting family apparently loves custom luggage. A Titan luggage spokesperson tells E!, “A celeb couple that not only travels ONLY with our luggage but has also been known to buy it as presents is Gwen Stefani and Gavin Rossdale. We also did a special bag line just for their son Kingston that is not available for anyone to buy.”

FYI: Gwen is using her Mamas & Papa’s Mylo stroller!

Gwen also is using Peg Perego Skate stroller.
