Announcing the news of Ruehlemann's death, his agent, Jason Kanner, from Soul Artist Management, wrote: "It is with great sadness and a heavy heart that I let you all know that Jeremy Ruehlemann has passed away. Jeremy was authentically himself. Salt of the earth. There was just something about him that made you root for him.
"His excitement over a big booking... his optimism when something didn't work out. When you spoke to him, he listened with his eyes and ears. He truly was and will always be one of a kind. Jeremy you will be missed."
Designer Christian Siriano wrote on Instagram: "I have never posted anything like this but to lose a friend who was such a beautiful soul is just really hard.
"This is for Jeremy, the most beautiful man that gave so much love to everyone he met no matter what. He was one of my muses, and he always will be.
"He inspired me and I will love him forever. I'm sending all my love to his family and friends who lost someone so special.
"I know we will meet again one day but right now I just want to hug him.
"Rest well J we all love you so much! Send love to his family today please."

I was with Jeremy on Thursday and in that moment I didn't know that kissing you and holding you for the millionth time would be the most memorable day of my life.
"I feel so blessed to love you and be loved by you. There will never be any way that I can sum Jeremy up in one caption… he was my chosen family and I will forever live for him.
