'Real World' Star Ryan Knight's Girlfriend Reacts to His Death & Her Message Is Heartbreaking — PHOTO

This is so sad. In a new message posted on her Instagram account, Makenzie Jauer, the girlfriend to late Real World star Ryan Knight, posted a heartfelt, touching tribute to her boyfriend, who passed away just yesterday at the age of 29. Like the messages of condolences from Knight's Real World and The Challenge co-stars, Jauer's message was heartbreaking:

I love you Ryan Knight. I am heartbroken, confused, hurt and most of all mad. The pain I am feeling now will never go away. You mean more to me than you will ever know & I never thought that I would spend a day without you. Every second with you was full of love and laughter. You were the brightest light in every room. You taught me not to care about what other people think and you made me understand that being myself was okay. Thank you for being inappropriate at the worst of times and making me laugh until I cried. Thank you for loving me unconditionally even though I snored and drooled on you in my sleep. You had the sweetest soul and I will never forget that. I always called you "my sweet angel" and now you truly are. Love you forever, MEKFollow

Along with the tribute, Jauer included a series of cute, candid snapshots of her and Knight together.

As previously reported, Knight passed away on Thursday at the age of 29, after a night of partying with friends. Though the official cause of death has not yet been released, sources close to Knight reportedly told TMZ that the tragedy may have been accidental.

Knight's death is the second tragedy to hit the Real World franchise in recent weeks: Just earlier this month, Real World and The Challenge star Diem Brown passed away at the age of 32, after a long battle with cancer. Both Brown and Knight appeared in the same season of The Challenge together, and, upon hearing news of her death, Knight changed his Twitter profile picture to a shot of him and Brown on a beach together. The heartbreaking photo remains on his Twitter page at this time.

His final post on Instagram was also a sweet tribute to Brown:
