Julianne Hough was just 18 years old when she joinedDancing With the Stars as a professional dancer during Season 4 in 2007. She came onto the show with a bang, winning her first two seasons with partners Apolo Anton Ohno and Hélio Castroneves.
Hough only served as a pro on the show for five seasons, but she stayed part of the family. She eventually became a guest judge, then a full-time judge, and now, a cohost. For the show’s 20th Anniversary Celebration episode on Tuesday, November 11, she’ll reunite with Ohno, as he’s returning to the show to take part in the dance relay with Season 34 contestant Jordan Chiles.
