Ellen DeGeneres is mourning the loss of her friend.
"I'm heartbroken. tWitch was pure love and light. He was my family, and I loved him with all my heart," DeGeneres told E! News in a statement. "I will miss him. Please send your love and support to Allison and his beautiful children - Weslie, Maddox, and Zaia."
The comedian also posted her note to Instagram, alongside a photo of the two hugging.
After joining the daytime talk show in 2014, Boss quickly became a fan favorite, becoming co-executive producer on the series in 2020 until its end in 2022, during which he often filled in for DeGeneres as host.
In one of the final episodes of her talk show in May, DeGeneres gave Boss a special sendoff in a surprise tribute where she reflected on how they first met along with the close bond they've formed.
"Over a decade ago, I met someone who changed my life, and our show," the comedian said. "I'm talking about you, tWitch."
"I love you so much and it's been an emotional week," DeGeneres added before pointing out that Boss' mom coincides was in the audience that day. "You always make me smile and laugh. We put together a little something together just to say how much we all love you here."
The Finding Dory star then played a recorded video of herself reminiscing on some of her favorite moments with him. "Whenever he's not here—for whatever reason—it's just different," DeGeneres said in the clip. "I mean, I count on him to look over at and make silly jokes. He's my pal. He's my sidekick. We have this connection, just looking over and he makes me laugh. He really, really makes me laugh."
She continued, "I love you, tWitch. We tell each other that every day when we say goodbye after the show. We both say, ‘Love you.' He says, ‘Love you much,' and I say, ‘Love you.' So, he's never gonna be out of my life. He's always gonna be a part of my life."
DeGeneres' statement is one of several tributes from Ellen DeGeneres Show colleagues. The show's executive producer Andy Lassner posted a screengrab of him with Boss and DeGeneres in a car from an episode, writing, "Rest, my friend."
Kalen Allen, who provided commentary on the talk show, shared a moving message on Instagram to to his "beloved friend, confidant, and brother."
"God knows, my heart is at a standstill because I have never known a friend like you," he continued, alongside several snaps of the pair together. "No words, dance, or show can adequately capture just how magnificent your existence was to this world and me. 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."
Allen also noted how much his friendship with Boss meant to him 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," he shared. "Oh, my friend, you have no idea how your existence alone was revolutionary. To be heard is one thing and to be seen is another. But, to be felt is the true gift, and I hope that as you look down from above, you know that you were never anyone's sidekick, and hell, you weren't even a real DJ, lol. 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. "
"It is with the heaviest of hearts that I have to share my husband Stephen has left us," she stated. "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."
Prior to his time at The Ellen DeGeneres Show, Boss appeared as a contestant on several competition shows, before rising to fame as a runner up on So You Think You Can Dance in 2008. He later appeared in an All-Star season and returned as a judge. Along with Holker, he also hosted Disney's Fairy Tale Weddings.
