The Rossdale Brothers Visit The Zoo

Four-year-old Kingston took his little brother Zuma for a spin as the boys, along with a nanny, visited the Los Angeles Zoo yesterday (June 21). Parents Gwen Stefani and Gavin Rossdale weren't spotted on the outing.

Zuma, who celebrated his first birthday last August, was wearing a cute T that read, "Good life begins at 1!" Here's a flashback: Kingston wore the same shirt to mark his birthday three years ago!
