83. Serena Williams
Age (circa 2009): 27
Currently the world's second-best female tennis player (but the #1 most paid), Serena has dominated the sport for the past decade, winning Wimbeldon four times and brining home two Olympic gold medals. It's enough to make us forgive her for dating Brett Ratner.
Winning both Wimbledon and the U.S. Open in 2009. She's da best, mayne!
