A back and spine injury may have retired Anna Kournikova from tennis, but her funds and work have not slowed down. It’s debatable whether or not she could hold her own place on a list of names featuring the best female tennis stars, considering her success on the court came mainly from playing doubles. She never won a single’s title. Now, she can be seen in minor roles on the big screen. She also isn’t shy about showing a little skin as a model.
