Stephen 'tWitch' Boss has died aged 40, it has been reported.
The DJ, who became known for his appearances on the Ellen Show, has died from apparent suicide, TMZ has reported.
Stephen started DJing on Ellen's show in 2014, and remained with the show till it ended earlier this year.
Ellen made Stephen an executive producer on the show in 2020.
Stephen's wife Allison Holker is said to have run into an LAPD station on Tuesday after she was left deeply concerned he had left home without his car, which was unlike him, a law enforcement source told the online publication.
A short time later, it has been reported that the police received a call for a shooting at an LA hotel, where Stephen was found dead from an apparent self-inflicted gunshot wound.
Ellen paid tribute to her dear friend on Instagram, sharing a picture of the pair hugging.
She expressed her sadness in the caption, writing: "I’m heartbroken. 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."
Just weeks before he died, Stephen shared a touching message on Twitter.
"One of my favourite parts of flying on a cloudy day is when the plane breaks through the clouds to reveal the beautiful day that's just beyond the cloud ceiling.
"A great reminder for life on the vastness of the idea that 'everything will be alright'.
"And if we can just know, have faith that just beyond whatever clouds are on our perceived ceiling, are clear skies full of potential possibilities and promises," the DJ wrote in one of his last social media posts.
Tributes have been pouring in for the star, with singer Tamar Braxton commenting on Allison's latest Instagram post: "Sisssssssster my heart is broken. I’m sooooo sorry."
Real Housewives of Miami star Larsa Pippen added: "Praying for your family."
"Heartbreaking I am so sorry for your loss. Sending love and light to your beautiful family," penned Kyle Richards.
Stephen's So You Think You Can Dance co-star Rudy Abreu wrote: "My heart is broken right now finding out this news… I am so sorry and I love you.."
Stephen first stepped into the spotlight back in 2008, when he wowed with his dance skills on So You Think You Can Dance.
Stephen made the move into the acting world and appeared in several shows before starring as Jason in Step Up, and later Magic Mike XXL.
Following the end of the Ellen Show, Stephen appeared to be happy spending more time with his three children — Weslie, 14, Maddox, six, and Zaia, three — and wife, who he married in 2013.
Stephen and Allison celebrated their ninth wedding anniversary just three days ago.
Paying tribute to her husband, Allison took to Instagram to share a video from their special day. Alongside it, she wrote: "It’s our 9th anniversary!! I couldn’t be more grateful to celebrate this perfect magical day!!!
"Saying YES to @sir_twitch_alot has been one of the best decisions I have ever made in my life!!"
Allison added: "I feel so blessed and loved!! I love you baby and I will never take you or OUR love for granted! I LOVE YOU."
