Gwen Stefani & Family: Fun At Sea

Gwen Stefani carried son Zuma, 2, as she waved from the deck of a yacht in Antibes, France on Saturday (May 14). Little Zuma doesn't look very happy here.

But he cheered up later when he and big brother Kingston, nearly 5, joined dad Gavin Rossdale for a ride on a jet ski.

The No Doubt rocker is at the Cannes Film Festival fulfilling her duties as a L'Oreal ambassador – she was named the new face of L’Oreal Paris in January.
