Glamorous Gwen Stefani Treats Her Boys to Tennis

Gwen Stefani's eldest kids had a special Sunday with their mom, hitting up the BNP Paribas Open in Indian Wells, CA. Kingston, Gwen, and Zuma watched attentively as Roger Federer and Novak Djokovic squared off on the tennis court. At one point, Kingston yelled out something while Gwen lit up with a smile. Although the singer and her cute sons sat near other fans, she stood out in hot-pink sunglasses.

Tennis seems to be one of Gwen's favorite sports. Last September, the star brought her baby Apollo to multiple matches at the US Open, marking the little guy's first public outings. We most recently caught a glimpse of Gwen when she stepped out for an appointment in LA earlier this month. The singer turned heads with her Marilyn Monroe-inspired look.
