The judges of "Dancing with the Stars" are Carrie Ann Inaba, Bruno Tonioli, Len Goodman and Julianne Hough. Inaba, Tonioli and Goodman have been on the ABC show since the series first aired in 2005.
Inaba, Tonioli, Goodman and Hough are permanent judges, but a number of celebrities, including Ricky Martin and Cher, have served as guest judges.
The four judges of "Dancing with the Stars" take part in eliminating one pair of dancers each week on the show. Audience votes also determine which contestants are eliminated and which ones advance to the next round the following week. Each contestant pair is composed of a celebrity and a professional dancer.
