Stephen “tWitch” Boss, choreographer, DJ and co-host of “The Ellen DeGeneres Show,” has died. He was 40. 

According to a report from the Los Angeles medical examiner, Boss died by suicide at a hotel Tuesday, December 13. 

Boss, known as “tWitch” on DeGeneres’ long-running syndicated daytime talk show, joined the show as a guest DJ in 2014 before becoming a permanent fixture and later being named the show’s co-executive producer in 2020.  (“Ellen” ended its 19-year run in May.) 

The Montgomery, Alabama, native, who started dancing at 16, competed on the fourth season of Fox’s “So You Think You Can Dance” in 2008 and finished in second place. He first caught DeGeneres’ attention in 2010, when he was part of the cast of “Dance” and worked with DeGeneres on a routine, a moment DeGeneres called “a crash course in getting to know each other.”

Boss was invited on “Ellen” in 2013 as a guest DJ before becoming a show staple the following year. He hyped up the studio crowd with the signature dance session that started every episode of the show. 

In addition to his gig on “Ellen,” Boss appeared in 2015’s “Magic Mike XXL” and films in the “Step Up” franchise.

His wife, dancer Allison Holker, shared a statement about his death to People magazine. 

“It is with the heaviest of hearts that I have to share my husband Stephen has left us,” she said. “Stephen lit up every room he stepped into. He valued family, friends and community above all else and leading with love and light was everything to him. He was the backbone of our family, the best husband and father, and an inspiration to his fans.”

“To say he left a legacy would be an understatement, and his positive impact will continue to be felt,” her statement continued. “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 especially for our three children.”

She ended her tribute, “Stephen, we love you, we miss you, and I will always save the last dance for you.”

Days before his death, he celebrated nine years of marriage with Holker, 34, on Instagram Saturday, sharing three images from their 2013 wedding.
