Ciara in a Pink Sequined Bikini in Miami Beach Pictures

Ciara tied on a sexy string bikini covered in pink sequins as she took a dip in Miami Beach today. The singer is one of several celebrities taking advantage of the scene in Florida during Mercedes-Benz Fashion Week's 2012 Swim Week. Whitney Port and Kristin Cavallari have also gotten in on the action, hitting the beaches, pools, runway shows, and parties. Ciara enjoyed some R&R this afternoon, but her trip wasn't all play. She also performed at the first of 10 Summer concert tour dates in Miami over the weekend. The pop star, who is joining Taio Cruz for the series of shows, also might be heading back to the recording booth soon. Ciara is one of several artists expected to join Epic Label Group now that music industry veteran L.A. Reid has taken over.
