Sports Illustrated model Julie Henderson shows off enviable frame in skimpy bikini as she frolics with boyfriend in Miami. He’s not pictured because we’re not interested in looking at some bulky dude. She made a name for herself as a Sports Illustrated swimsuit model. Julie Henderson certainly heated things up with her bikini body in Miami on Saturday. The Texas native, who turns 28 on Wednesday, slipped into a skimpy two-piece as she frolicked in the ocean. Julie wore string neon bottoms and a low-cut purple bikini top, and wore her blonde hair in loose waves. Nice match.
