Gwen Stefani has enjoyed traveling with her youngest son. The No Doubt singer – who has two boys, Kingston, three, and 13-month-old Zuma with husband Gavin Rossdale – has just returned from a trip with her band to Russia and was pleased to have some time alone with Zuma.

Gwen - who played a private concert with her band in the country - said:

“It works out well to have just Zuma with me because now it is one-on-one for him, which is really special. He has really blossomed in the last few days. It has been perfect. I knew I couldn’t be without him.”

Gwen has previously spoke of her worry about taking her children on tour as she wasn’t sure how her No Doubt bandmates would cope with her growing entourage.

Before, when I was with the guys, I didn't have any kids. That's like, whoa, a huge deal. The dynamic of the band is different. It has to be.

"I've got two babies and their nanny, and an assistant, and my security, and a hairdresser. It's not as much of a party, but that's what I need in order to perform every night."

It's funny because her personal life has certainly matured, but when you see her bouncing around on stage during a concert, I feel like I am still in the 90s. The energy that woman has!! :)
