"It is with the heaviest of hearts that I have to share my husband. Stephen has left us," wife Allison Holker Boss said in a statement to People Magazine.

"To say he left a legacy," she continued, "would be an understatement, and his positive impact will continue to be felt. I am certain there won't be a day that goes by that we won't honor his memory. We ask for privacy during this difficult time for myself and our three children. Stephen, we love you, we miss you, and I will always save the last dance for you."

Boss, known as "tWitch" on the "Ellen DeGeneres Show," joined as DJ in 2014 before becoming the show's co-executive producer in 2020.

Boss also gained social media fame performing with his wife and fellow dancer Allison Holker Boss on videos, which garnered Holker more than two million Tik Tok followers.

"All the dances that we're creating, whether it be on Instagram, or if it's on TikTok, it's us as a family, legitimately just having a good time together," she said on the "HollywoodLife" podcast. "I feel so humbled and honored that everyone loves watching that, because it's just a way for the family to connect and laugh together."

The couple celebrated their ninth wedding anniversary on Dec. 10.

Holker shared a post to Instagram to mark the occasion, in which she said she "couldn't be more grateful" to be married to Boss and that saying yes to him was "one of the best decisions I have ever made in my life."

An autopsy has been scheduled.
