Kate Gosselin
From the very onset of Season 10, it was apparent that reality-television mom Kate Gosselin had been cast more for her dramatic and ratings-grabbing personality than for her dancing chops. Gosselin, who famously berated her ex-husband for breathing too loudly on their show, Jon & Kate Plus 8, brought her critical tone with her to the Dancing with the Stars set, where she immediately clashed with partner Tony Dovolani over his instructional style (he wanted to quit by the second episode). For all the theatrics off stage, though, Gosselin was unable to bring any life to the dance floor, where judges dubbed her stiff and awkward debut performance to Billy Joel's "She's Always a Woman" a "nightmare." The duo danced the paso doble to Lady Gaga's "Paparazzi" in week three, but not even the pop maven's catchy megahit could pump any energy into the reality star's performance. Judges slammed her for "going through the motions like a Stepford wife." Gosselin's dismal moves kept her at the bottom of the barrel throughout her time on the series, and by the fifth week, the TV mom was eliminated. Only then did Gosselin's emotions come through, as she delivered a teary goodbye to the judges and crowd.
