Cast in the 20th season of the Real World and the third season of Celebrity Rehab, 29-year-old Joey Kovar was found dead at a friend’s house in the Chicago area earlier today.

According to reports from the Chicago Ridge Police Department, paramedics arrived in Bedford Park, IL to find Kovar with blood coming out of his ears and nose. He was pronounced dead upon the arrival. An autopsy is pending; however, according to TMZ, his family suspects that drugs were involved in the incident.

During his stint on Celebrity Rehab, the aspiring actor and body-builder struggled with cocaine and ecstasy addiction. He famously left the Real World: Hollywood cast mid-season to enter rehab after admitting his abuse of drugs and alcohol.

Kovar is the fourth former Celebrity Rehab star to die in the past 18 months, after the deaths of Jeff Conaway, Mike Starr, and Rodney King.
