Gwen Stefani was out and about with her children this week, starting their holiday festivities a little early.

According to Bauer-Griffin, the singer and her sons, Kingston, 5, and Zuma, 3, enjoyed the sights at Griffith Park's Travel Town museum, where they rode a train -- something the kids really seemed to enjoy.

Stefani, who launched her Harajuku Mini for Target children's clothing line last month, recently told InStyle that she loves styling her sons.

"When I had kids, I was like, 'Boys? What?' But I've had so much fun dressing them. I love it!" Stefani said, adding, "They teach me to mind my own business and let them dress how they want."
