Gwen Stefani took a break from her London press schedule to spend time with her son Zuma Rossdale yesterday. They walked hand in hand before heading to dinner at Ozer Restaurant. Gwen sported a black silk jumpsuit and houndstooth blazer, along with a pair of studded spike booties from Giuseppe Zanotti. Gwen has been overseas with her No Doubt bandmates to promote their new album, Push and Shove. No Doubt's sixth studio album has gotten great reviews so far, and the band is headlining shows at LA's Gibson Amphitheatre this November and December, with tickets on sale today.
