Gwen Stefani's Family Beach Day

A growingly pregnant Gwen Stefani and her husband Gavin Rossdale took their son, Kingston, for a day of fun at the beach in Santa Monica on Saturday (April 12).

During the course of the shoreside outing, Gavin and Kingston played in the water while Gwen watched. The happy family then took a long stroll down the boardwalk, posing for pictures along the way.

In related news, the Hollaback Girl singer and her rocker husband have decided to wait until birth to find out the sex of their unborn child, just as they did when Gwen welcomed their two-year-old son Kingston into the world in 2006.

"We don't know (the baby's sex). It was a surprise last time so we're kind of working on that this time," Rossdale told Ryan Seacrest on his KIIS-FM radio show.
