Los Angeles, Sep 25 (IANS): Singer Gwen Stefani says it was a magical moment for her to take her three sons -- Kingston, Zuma and Apollo -- on a tour for the first time.

Stefani appeared on the "The Ellen DeGeneres Show" to promote her new animation series "Kuu Kuu Harajuku", read a statement.

When asked about the tour, Stefani said: "It was insane, and also it was magical thing because I think for me, now that I'm a mother, I really hadn't toured with the boys.

"And having them out there, but also, seeing dads who were, like, tatted up, they'd probably been like old school. No Doubt fans — with their daughter on their shoulders, like their first show. And it was just kind of the whole thing was full circle and magical."

Stefani even shared that they felt "guilty" of bringing them on tour with her because they "work so hard at school all year".

"I have to drag them around in a bus all summer. But they had the best time. I mean it's a bus, it's a lot. Can you imagine three little boys on a bus after you do a show? Get to bed, it's like no. It's exhausting, but it was fun," she said.

The episode of "The Ellen DeGeneres Show" will be aired on Monday in India on Romedy NOW.
