You want a hot body? Britney Spears definitely works for it. The pop star was photographed rocking a neon pink bikini while on vacation in Hawaii with boyfriend David Lucado and her sons Sean, 8, and Jayden, 7.

The hard-working Planet Hollywood resident performer, 32, looked several shades darker after spending the day by her hotel pool in a fringed two-piece. Spears' famous figure looked toned and tucked with her lean legs on display and her brunette-again tresses swept atop her head.

Spears later took a refreshing walk along the beach and took a dunk in the Pacific.

The singer has been working hard lately staying in shape. Along with performing her dance-intensive routine as part of her two-year Britney: Piece of Me residency in Vegas, Spears was also photographed heading to the gym on March 12 wearing a bizarre sauna suit top.

Her latest Hawaiian excursion comes just two weeks after younger sister Jamie Lynn's March 14 New Orleans wedding to Jamie Watson. As previously reported by Us, Britney's sons were a part of the intimate ceremony, along with Jamie's daughter Maddie, 5, who was the flower girl.

The "very emotional" ceremony was full of tears and laughter. "After they were pronounced husband and wife, he turned to the audience and said, 'Yeah!'" an eyewitness told Us. "He was so excited and everyone was cheering."
