On Sunday, colleagues and close associates of fashion model Jeremy Ruehlemann sadly revealed that he passed away at the tender age of 27.

The cause of death for the young model remains undisclosed to the public.

Representing his home state of New Jersey, this model has graced the catwalks for fashionistas such as Christian Siriano, John Varvatos, and Superdry. In addition, he was featured in GQ magazine and Playhouse Magazine; a testament to his remarkable talent.

In a heartfelt post on Instagram Sunday, Siriano paid tribute to Ruehlemann.

“I have never posted anything like this but to lose a friend who was such a beautiful soul is just really hard,” the “Project Runaway” star posted. “This is for Jeremy, the most beautiful man that gave so much love to everyone he met no matter what.”

Siriano expressed his admiration for the model, referring to her as one of his cherished “muses.” He also conveyed his sincerest condolences to those grieving this tremendous loss.

Lexi Wood, a fellow model, tearfully posted an emotional tribute to her “soulmate” and “best friend”, Ruehlemann.

“[I]f you have ever known me you know how much I love Jeremy,” she wrote in an Instagram post. “I can’t even articulate the magic that he was. I met Jeremy when I was 15, the day I met him I knew my heart would be full forever, he’s my soulmate, my best friend, my support, my family, my light, my love, my twin flame… I could go on and on because he was so special.”

The post included a compilation of pictures together and love-filled messages from both parties, expressing their profound affection for one another.

Wood remarked that she and Ruehlemann had only met the Thursday prior.

“But I think what was the most special thing about him was that he was walking sunshine, he made everyone feel like they were the most special in the room, when he went anywhere it was like there was a light beam on him,” Wood continued. “His love will eternally flow through this world.”

Demi Lovato shared her sympathies over Instagram, offering a heartfelt response to the post.
