3. Anna Kournikova
Country: Russia
Sport: Tennis
Years: 1995-2007
I’m sure you all heard about her and her career. But most of you may know her as the girlfriend of singer Enrique Iglesias.
Although she never won a WTA game she made her way into the world by other means. She is the best known tennis star worldwide.
Her success came when she chose to play doubles where she was at that time the World No. 1 player.
Is a bad thing her career ended when she was only 21 because of the serious back and spinal problems including a herniated disk. Now she only plays in occasional exhibitions.
