In her early teens, Kournikova signed a management deal and headed to Florida for tennis training with coach Nick Bolletierri, who compared her to John McEnroe. When she went professional at 15, she made it to the fourth round at the 1996 U.S. Open and the semifinals at Wimbledon in 1997. Known for dominating in doubles, Kournikova limited her playing to charity causes in 2004 due to injuries she sustained while playing competitively. Frequently named on lists of the most beautiful and sexy women, she is also one of the most searched people on the Internet. Aside from ongoing endorsement deals, Kournikova has recently expressed an interest in fencing.
