The Season 25 celebrities were able to choose their own songs to dance to with their professional partners -- songs that best represent the routine's meaning and spirit. The celebrity and professional pairings will be performing the Viennese waltz, foxtrot, rumba, quickstep, waltz, or a jazz or contemporary number.
Jordan will be celebrating 2005, when he was officially adopted by his grandparents. Nick will re-live 2011, which was the year he married Vanessa.
Vanessa will dance in honor of 2016, the year her son Phoenix was born but 10 weeks premature.
Nikki will be revisiting 2015, when she had to go through a possible career-ending surgery to mend her broken neck. And Victoria will rejoice to 2017, when she was no longer paralyzed and competing in a reality dancing competition show.
ABC didn't reveal the years the remaining celebrities will celebrate on the upcoming episode.
