Jennifer Lopez, JoJo Siwa, Dwayne Johnson and more pay tribute to Stephen 'tWitch' Boss

Friends, peers and loved ones are mourning the loss of DJ, choreographer and television personality Stephen "tWitch" Boss, who died this week at the age of 40.

The Los Angeles County coroner determined the cause of death to be suicide, ABC News has learned. Boss' body was found Tuesday at a motel on Ventura Boulevard and he was declared dead at 11:25 p.m. local time.

The television personality is known for being a DJ and frequent guest host on "The Ellen DeGeneres Show." He served as the talk show's DJ until it ended this year. Boss also teamed up with DeGeneres on "Ellen's Game of Games," which aired from 2017 to 2021.

Following news of Boss' death on Wednesday, DeGeneres took to Instagram sharing a photo of her and Boss hugging.

"I'm heartbroken," DeGeneres wrote. "tWitch was pure love and light. He was my family, and I loved him with all my heart. I will miss him. Please send your love and support to Allison and his beautiful children -- Weslie, Maddox and Zaia."

Boss' wife, fellow dancer Allison Holker, issued a statement confirming her husband's death earlier on Wednesday, saying, "It is with the heaviest of hearts that I have to share my husband Stephen has left us."

"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," she continued. "He was the backbone of our family, the best husband and father, and an inspiration to his fans."

Holker added, "To say he left a legacy 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 especially for our three children."

In addition to being part of "The Ellen DeGeneres" show, Boss competed on season 4 of "So You Think You Can Dance," finishing as the runner-up, and returning to the show in following seasons as a featured all-star. He returned as a judge for season 17.

Boss and Holker, a fellow "SYTYCD" alum who competed in season 2 and returned as an all-star in subsequent seasons, married in 2013. They celebrated their ninth wedding anniversary on Dec. 10.

To mark their anniversary, Boss took to social media to share a photo of himself and Holker dancing at their wedding and showing off their wedding bands.

In addition to adopting Holker's daughter Weslie, from a previous relationship, Boss and Holker shared two children, Maddox Laurel, 6, and Zaia, 3.

Below, see how others are paying tribute to Boss this week.

Kalen Allen: "To my beloved friend, confidant, and brother… God knows, my heart is at a standstill because I have never known a friend like you.

"In a world where it was easy to get lost in the shadows, I am grateful that we always saw each other. We were each other's number one fan and often the light in each other's darkest hours. I am very sorry that the darkness found a voice this time and became too loud."

"On a more personal note, as a queer black man, I want to thank you for seeing me and providing me with a friendship that I didn't even know could exist," Allen added. "But how you moved and captured the hearts of the world with your gentle and subtle kindness was the glue that made the puzzle complete. We ended every show encouraging the audience to take whatever light and joy they found in that soundstage and spread it through the world. I promise you I'll dream the unimaginable. I'll climb every mountain, and I'll dance every single dance with your memory as fuel."

Twitch, I'm at a loss... my heart seems to be frozen... like I don't want to exhale, hoping that maybe if I don't exhale, that someone will correct this horrible mistake. And all will be okay again. My prayers are joining with all the other prayers going out to @allisonholker and your family... sending them love and so much support."
