At the dawn of the new millennium there were no bigger female sports stars than Serena Williams and her sister Venus. The sizzling sisters used their on-court talents to capture all of tennis’s top honors, including gold medals at the 2000 Summer Olympics. While those skimpy little tennis skirts put spring in Mr. Skin’s racket, it’s off the court that younger sis Serena made her biggest impression. She started appearing as herself at the height of her tennis career on shows like The Simpsons and America’s Next Top Model before plunging into a proper acting career with guest spots on shows like My Wife and Kids and Law & Order: Special Victims Unit. Mr. Skin prefers the 2005 reality television series Venus and Serena: For Real, though, especially the episode “Sibling Rivalry”, in which Serena displays her fabulous athletic curves in a hot-pink bikini during a poolside photo shoot.
