Joey Kovar is dead at age 29, according to TMZ. The former reality star, who appeared on "Real World: Hollywood" and "Celebrity Rehab 3", was reportedly found in a friend's home in Chicago Friday morning.
Kovar, who once worked as a personal trainer, bodybuilder and aspiring actor, has had a long history of drug abuse and his family suspects he died from a drug overdose, according to the site.
In 2008, Kovar's time in MTV's "Real World" house was cut short when he entered a 30-day rehab facility halfway through the season for alcohol problems. He later left the show, fearing a relapse.
Kovar also appeared on the third season of "Celebrity Rehab," in 2010 with hopes to overcome his addiction issues with alcohol, cocaine, ecstasy, methamphetamine and steroid use.
