Christian Siriano is grieving the loss of a dear friend.
The designer recently shared that model Jeremy Ruehlemann has died.
"I have never posted anything like this but to lose a friend who was such a beautiful soul is just really hard," he wrote on Instagram Jan. 22. "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."
Siriano went on to express his condolences to Ruehlemann's loved ones. "I'm sending all my love to his family and friends who lost someone so special," he continued. "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."
"Goodbye Sweet Jeremy," he wrote on Instagram Jan. 22. "R. I. P. Jeremy Ruehlemann. Love to your family who you adored, as much as they love and adored you. I am heartbroken."
Ruehlemann's modeling agent also confirmed his passing to E! News. A cause of death has yet to be revealed.
In addition to modeling in several of Siriano's runway shows, Ruehlemann appeared in presentations for brands like Atelier Cillian and Joseph Abboud. He was also photographed for editorials in publications such as GQ and Playhaus Magazine and worked with clothing companies like Superdry and Perry Ellis.
Just days before news of his death broke, Ruehlemann posted a behind-the-scenes picture from what appeared to be a photo shoot with the brand Tommy Hilfiger to Instagram, captioning the snapshot, "Bts with Tommy."
