A decked-out Gwen Stefani hosted a private Harajuku-themed charity tea party at Royal/T in L.A. to benefit Save the Children’s Japan Earthquake Emergency Fund. Stefani was joined by sons Zuma, 2½ and Kingston, 5, as well as her mother, father, and hubby Gavin Rossdale at the event. The kids enjoyed themselves, playing with toys in the venue’s pop art installation, while Stefani serenaded the crowd with hits like “It’s My Life” along with her No Doubt bandmates.
