Stars We Lost in 2013: Cory Monteith

Four years before his tragic passing in a Vancouver hotel room, Cory Monteith (then the fresh-faced star of a little-known FOX comedy called Glee) gave ET a tour of his new Los Angeles residence.

The Canadian native admitted that he and his roommates liked to entertain at their bachelor pad: "There's the indoor bar and the outdoor bar," said Monteith, who assured ET that he refrained from drinking during their popular bashes -- one of which was inspired by the Rat Pack.

"I guess there was four or five hundred people here and they use all these martini glasses and they make a big production out of it," said Monteith.

The actor then showed ET his room -- bare and basic.

"I'm never really here to be in my room," Monteith explained. "I'm always shooting a television show."

The actor's death was determined to be caused from a mixed drug toxicity involving heroin and alcohol. Four months before being found deceased on July 13, Monteith had admitted himself into a treatment facility for substance addiction.

This fall, Glee honored their fallen star with a special tribute episode, featuring a heartfelt performance from Lea Michele.
