Who You Didn’t See on “Dancing with the Stars ”20th Anniversary Special

Dancing with the Stars celebrated 20 years on the air with a ballroom full of familiar faces.

On Tuesday, Nov. 11, the beloved dance competition series, currently on season 34, honored two decades since making its debut in 2005. While many took the dance floor again, there was no shortage of former pros and stars who watched from the audience to mark the special occasion and cheer on the remaining seven couples currently competing for this season’s mirrorball trophy.

Several champions were spotted in the audience, including actress and season 1 winner Kelly Monaco, figure skater and season 6 winner Kristi Yamaguchi, gymnast and season 8 winner Shawn Johnson and NFL player and season 14 winner Donald Driver.

Also in the ballroom were comedian Bill Nye from season 17, reality stars Ariana Madix, Charity Lawson and Mauricio Umansky (joined by daughter Alexia Umansky) from season 32 as well as Olympians and season 33 finalists Stephen Nedoroscik and Ilona Maher, the latter of whom who was sitting with sitcom actor and season 1 runner-up John O’Hurley.

Other notable named included reality star Trista Sutter from season 1; actor Cameron Mathison from season 5; Oscar winner Marlee Matlin from season 6; Paralympic medalist Amy Purdy and actresses Candace Cameron Bure and Danica McKellar from season 18; influencer Bethany Mota from season 19; reality star and season 23 semi-finalist Terra Jolé; and Spanish artist Charo from season 24.

Tom Bergeron even returned as a guest judge — alongside original panelists Carrie Ann Inaba and Bruno Tonioli as well as pro-turned-judge Derek Hough — after leaving the show in 2020 following 28 seasons as the host.

A select few eliminated stars from the current season also returned for DWTS’ birthday: Scott Hoying was seen supporting the cast with husband Mark Manio along with Danielle Fishel and her husband, Jensen Karp.

Lindsay Arnold, who was a pro from seasons 16 and 21 showed up to celebrate both the show and her younger sister, Rylee Arnold, on her second season as a pro. Maksim Chmerkovskiy, whose brother Val Chmerkovskiy and partner Alix Earle received their first perfect score of the season in this episode, sat in the audience as well.

Sharna Burgess also stopped by for the big event after making her exit after 14 seasons as a pro. Her final competitive season was in 2021, when she was partnered with her now-fiancé, Brian Austin Green. Another recognizable alum in attendance was Anna Trebunskaya, who competed for a total of 11 seasons.
