Gwen Stefani & Gavin Rossdale's Beach Boys

Gwen Stefani and Gavin Rossdale enjoyed a day at the beach in St. Barts, French West Indies with their two sons - Kingston, 4, and Zuma, 16 months - on Monday (January 4). The bikini clad songstress rocked her amazing abs that rivaled her husband's as they walked hand in hand with Kingston in between resting in the shade with Zuma and building sandcastles.

Gwen recently said that her current figure is “no miracle” and that it took eight months to lose the baby weight after her pregnancy with Zuma.

The Stefani-Rossdales have been vacationing in St. Barts after spending the holiday season at their London home.
