For the second time this month, former cast members of MTV’s Real World are mourning a colleague. Ryan Knight, who appeared on the 2010 New Orleans edition of the long-running reality show, was found dead Thursday morning. He was only 29.

Knight’s friends told TMZ that Knight was out partying Wednesday night and they found him dead the next morning at a friend’s house. He had choked on his own vomit, the friend said.

Sources told the site that Knight took “some pills” during the partying, but were not clear about what else he did that night. However, they say he was upbeat and told people he was dating someone.

Knight is the second Real World star to die this month. Diem Brown, who also appeared on The Challenge, died at age 32 following a battle with ovarian cancer.

The two are not the first stars of the series to die young. Two years ago, Joey Kovar died at age 29 after struggles with drug abuse.

As MTV notes, several other former Real World stars took to social media to mourn Knight’s death. His on-again, off-again girlfriend, Jemmye Carroll shared pictures of happier times with him.
