The “Real World” family has lost another member.

Ryan Knight, who appeared on the 2010 “Real World New Orleans” season as well as “The Challenge,” has died, according to TMZ. He was 29.

MTV was unable to verify the reports independently, but has been posting condolences on its Twitter feed and related accounts.

According to TMZ, Knight was partying with friends Wednesday night in good spirits and ended up at a friend’s house. He was reportedly found dead by a friend the next morning. No cause of death has been announced yet.

The news comes barely two weeks after fellow MTV reality star Diem Brown died at the age of 32 after losing a battle against ovarian cancer. Brown and Knight appeared on “The Challenge” together, and Knight posted a heartfelt tribute to her on Twitter the day before her funeral.

“Real World” and “The Challenge” alumni have taken to Twitter to mourn the loss of Knight since news broke.
