"Dancing with the Stars" is waltzing into its 20th year.
The reality dance competition, currently in its 34th season, will celebrate its 20th anniversary with a special episode on Tuesday, Nov. 11.
Celebrities and professional dancers from all seasons will come together on the dance floor to honor the show's two-decade history, and the original "DWTS" host, Tom Bergeron, will serve as a guest judge.
Below, take a look back at some of the biggest moments in "DWTS" history over the past 20 years.
2005: 1st Mirrorball Trophy awarded
"General Hospital" star Kelly Monaco won the first season of the show in 2005 with professional partner Alec Mazo. After scoring low in Week 1, Monaco quickly bounced back as the underdog and ended up taking home the Mirrorball Trophy.
