Anna Kournikova sported a tie-dye bikini for a boat ride with Enrique Iglesias in Miami today. The longtime couple set sail near their Florida home and brought their two dogs along for the daytime cruise. Anna also showed off her bikini body in a white two-piece for a similar outing last month, shortly after celebrating her 32nd birthday. The retired tennis star recently got nostalgic about another milestone — Anna took to her Facebook page last week to post throwback photos of herself playing on the Wimbledon courts, saying, "I can't believe it has been 16 years since I played my first Wimbledon. Time flies!!"
