Gwen Stefani Rocks A Bikini At The Beach With Her Family (PHOTOS)

Rocker and fashion designer Gwen Stefani spent Sunday frolicking in the Malibu waves with her family, and X17Online snapped some photos that make it hard to believe Gwen is 41-years-old, let alone a mother of two.

Gwen seriously rocked the beach look in a tiny black bikini top and flowing, sheer, white skirt, as she played with her husband Gavin Rossdale and their two boys, Kingson, 5 and Zuma, 3.

And while we didn't know they were friends, we weren't too shocked to see the family stop to chat with Maria Shriver -- it is Malibu afterall.

Here's one pic of Gwen strolling down the beach, see the rest here.
