Charlize Theron shows off her toned physique in a black one-piece as she confidently rides a jet ski during Miami photo shoot. The 38-year-old looked phenomenal in a one-shoulder black swimsuit as she rode through the waves in Miami. The South African beauty displayed her muscular arms which featured criss-crossing ties on the side. She wore her short blonde hair wet and wavy, and sported natural make-up, save for a generous dusting of bronzer along her cheeks. The Oscar winner appeared to be having a ball, confidently steering the jet ski through the water. She had her adorable son, Jackson (not pictured) with her and she picked him up and showered him with hugs and kisses. Miss Theron changed into a total of four suits for that day’s photo shoot. A black one-piece swimsuit, a silver metallic bikini, a black bikini and a white bikini underneath a white dress (added a photo of each for a tease treat). Charlize can put on a paper bag and make it look totally couture. We love you Charlize!!
