It has been an extremely hard, sad couple of weeks for the Real World/Challenge family. Diem Brown lost her long battle to cancer earlier in November, and today, Ryan Knight—better known simply as "Knight"—was found dead, according to TMZ. He was just 29 years old.

Knight was reportedly out partying on Wednesday night, but was found dead by a friend this morning. He allegedly choked on his own vomit, and a source told TMZ that he had taken "some pills."

The reality star made his first appearance as part of the Real World: New Orleans cast. He went on to appear on several seasons of The Challenge. We can't even imagine how crushed his castmates are—losing Diem was devastating enough and now yet another charismatic friend has passed away.
