In what is believed to be his final video, Monteith is shown addressing his devotees while on a flight from Japan to Vancouver.
The 31-year-old was approached by an Air Canada flight attendant who asked him to say a few words on video for her boyfriend's daughter, who is a huge fan of the late star.
Monteith happily obliged and offered a few words of advice to the youngster, named Mallory.
In the clip, he said, "I wanted to record this video for you guys just to let you know to stay out of trouble and stay in school."
The seemingly final message from Monteith is just another shining example of how dedicated he was to Gleeks and making sure that he had a positive influence over his young fans.
Bravo has announced today that they will be re-airing the Glee episode of Inside the Actor's Studio, which originally aired in 2012.
In a now-chilling moment in the show's history, host James Lipton asks the actor: "If heaven exists, what would you like to hear God say when you arrive at the Pearly Gates?"
"Sorry I haven't been around, there's a good explanation," Monteith replied.
Glee's creator Ryan Murphy immediately responded to his answer by saying, "That's good. That's really good."
In a statement released by the network, Lipton recalled the star's response, saying, "I certainly hope there is [a good explanation]. We needed Cory's gifts."
"When I appeared as myself on Glee, I auditioned Cory's character, Finn, for the Actors Studio Drama School—and rejected him. That's the way Ryan Murphy wrote it," he further explained. "I would have admitted him—in a New York minute."
The tribute episode will air on July 18 at 6 p.m. and again on July 19 at 7 p.m.
