Gavin Rossdale & His Boys Feed Their Bellies

Gavin Rossdale took Kingston, 5, and Zuma, 3, out for lunch in Los Angeles, Calif. on Saturday (January 21).

As the family left Buddha's Belly restaurant, Zuma gave a smile as he was being carried by the nanny.

Meanwhile Gwen Stefani is busy working on the No Doubt album. She has explained why the band has been taking their time recording.

We do this thing where we work on it really hard, and then we take breaks, because everybody has so much going on. That's why it's taking so long.Everybody asks, 'Why is it taking so long?' Because I have kids. I'm a mom! I have school, I have homework. It's a lot."
