Anna Sergeyevna Kournikova (Russian: Анна Сергеевна Ку́рникова; born 7 June 1981) is a Russian professional tennis player who now is a Russian-American citizen. Her beauty and celebrity status made her one of the best known tennis players worldwide. At the peak of her fame, fans looking for images of Kournikova made her name one of the most common search strings on the Internet search engine Google.
Although reaching No. 8 in the world in 2000, she never won a WTA Title in singles. Kournikova's forte has been doubles, where she has at times been the World No. 1 player. With Martina Hingis as her partner, she won Grand Slam titles in Australia in 1999 and 2002. Based on their looks, Hingis and Kournikova referred to themselves as the "Spice Girls of Tennis". Kournikova's professional tennis career has been curtailed for the past several years, and possibly ended, by serious back and spinal problems. She resides in Miami Beach, Florida, and plays in occasional exhibitions and in doubles for the St. Louis Aces of World Team Tennis. She currently is the new trainer, replacing Jillian Michaels, on the television show The Biggest Loser.
Anna Kournikova was born in Moscow, Soviet Union, on June 7, 1981. Her father, Sergei Kournikov, was 20 at the time. Sergei, a former Greco-Roman wrestling champion, had earned a Ph.D. and was a professor at the University of Physical Culture and Sport in Moscow. As of 2001, he was still a part-time martial arts instructor there. Her mother Alla, who was 18 when Kournikova was born, had been a 400-meter runner.
