Cheater: Tiger Woods
Date Of Affair: Autumn 2004

Holly Sampson, labeled Tiger Woods' alleged mistress #7, states the world class golfer (and ass champ) only got lucky with her once—at his bachelor party. "Although I enjoyed our time together, I never was and never will be one of Tiger's mistresses," she told TMZ in in 2009. The porn star, who as a teenager had a role in a Wonder Years episode, is technically correct—a one-time one-in-hole with Holly before he was married would not make her a mistress. But it would want to make wifey want to scratch your face off like an angry tigress if she ever found out. (A bit of trivia for that ass: The lots-of-fun Tiger conquest Sampson often portrays cougars in her skin flicks.)
