Gwen Stefani Sexy Bikini Beach Pictures

Gwen Stefani slipped into a sexy two-piece and hit the beach with her family in Miami on Sunday. Gavin, Zuma, and Kingston Rossdale joined Gwen for a mid-Summer getaway. The family of four played in the sand, swam in the surf, and relaxed at the pool. Gwen modeled three different bikinis during the day, favoring zebra and leopard prints as well as a sporty black two-piece. Gwen's abs were on display during their beach time, and Gavin flashed his own impressive six-pack — don't forget to vote in our shirtless bracket!

Gwen appears to be enjoying a well-deserved break from work after sweeping through NYC last week to promote No Doubt's new album, Push and Shove. Gwen and the band performed their first single, "Settle Down," in Central Park and dropped by Late Night With Jimmy Fallon for an in-studio appearance. The group's got their sights set on Las Vegas, where they're scheduled to join musical acts like Rihanna, Usher, Taylor Swift, Pink, and more at this year's sold-out IHeartRadio music festival Sept. 21-22.
