No Doubt about it, Gwen Stefani has a body to be envied.
The 41-year-old rocker showed off her washboard abs and slender physique as she relaxed with her family aboard a luxury yacht off the coast of Antibes, France on Saturday.
Wearing a vibrant red and yellow animal print bikini with a striped floor length skirt, both from her own clothing line L.A.M.B, the singer stood on deck and watched as her husband Gavin Rossdale and son Zuma cruised around in the waves on a jet ski.
The No Doubt lead singer's elder son Kingston also watched the pair from aboard the boat.
The family has been vacationing this week aboard the floating palace, a 370 ft. yacht, which belongs to Russian billionaire Roman Abramovich.
