Petra Nemcova

Petra Nemcova was the fourth celebrity to be voted off "Dancing with the Stars."

The 31-year-old model and partner Dmitry Chaplin found themselves at the bottom of the leader board after their shaky quickstep routine in this week's patriotic theme. Watch the performance!

Nemcova, who was born in the Czech Republic, found herself in jeopardy alongside actress Kirstie Alley and wrestler Chris Jericho last night. Judge Len Goodman said neither Nemcova, Alley, or Jericho deserve to be kicked off the show.

A talk show host, a footballer, and an ex-Playmate are just part of the eclectic cast in Season 12 of "Dancing with the Stars."

Predictions on who will win have already started buzzing, with Kendra Wilkinson, Hines Ward, Kirstie Alley, and "Psycho" Mike Catherwood rounding up the final four.

"Extra's" AJ Calloway met with "Dancing with the Stars" Petra Nemcova, who revealed she is dancing with a purpose.

Nemcova created the Happy Hearts Fund after surviving the Thailand tsunami of 2004. The charity helps rebuild children's lives after a natural disaster. She told AJ, "My goal is to keep the light shining on those in Japan."

The stars of Hollywood are mobilizing to raise money and aid for Japan's tsunami victims -- including Lady Gaga designing a prayer bracelet, and P. Diddy, Conan, and Katy Perry using Twitter to get their fans involved in helping out. Charlie Sheen has also vowed to donate one dollar from every ticket sold to his comedy mini-tour!

"Dateline" reporter Ann Curry went to Japan and helped find a missing teacher after her family reached out to Curry via Twitter. After the emotional telephone reunion, the family tweeted, "Ann Curry I love you. Thank you for finding my sister."

Thailand tsunami survivor Petra Nemcova set the record straight and told "Extra" she will not be quitting "Dancing with the Stars" in order to pursue full-time work for her disaster relief charity. Nemcova plans to do both.
