Gwen Stefani’s Little Tennis Fan

Gwen Stefani and baby Zuma cheered on Roger Federer as he beat Fernando Gonzalez at the Indian Wells Tennis Tournament in California yesterday. The pop star and her 7-month-old son hung out with Federer's pregnant girlfriend, Mirka Vavrinec, as well as Gwen's younger brother, Todd.

Vavrinec, who happens to be a former pro tennis player from Switzerland herself, seemed to take a liking to little Zuma. Of course, who could resist a happy baby decked out in Burberry?
