Doting mother Gwen Stefani

London: Punk rock singer Gwen Stefani is all-excited about having her youngest son with her during her recent trip to perform in Russia. The `No Doubt` singer, who has two boys with husband Gavin Rossdale, said that she could not be on the trip without her 13-month-old son Zuma, reported Contactmusic.

"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," said Stefani, who played a private concert with her band in Russia. The 40-year-old singer had earlier expressed her anxiety 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," said the star. "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," she added.
