Monica Seles is one of the most celebrated female tennis players in history. A dancer? Not so much. The nine-time Grand Slam–winning player was kicked off Season 6 of Dancing with the Stars in a first-round double elimination after she and partner Jonathan Roberts danced the mambo. It seems the athlete had no trouble mastering the technical part of the show, but it was the showmanship side of dancing — especially important when the audience decides who stays and who goes — that was her downfall. "I just could not sell the performance," she said during an interview on Jimmy Kimmel Live. "I never missed a step, but yet I couldn't actually sell the story line."
