Cast mates of "Glee" star Cory Monteith took to twitter Sunday morning to mourn the loss of their fellow star on the hit Fox musical comedy series.

Just minutes after police confirmed Monteith's death, Mark Salling, who plays Noah "Puck" Puckerman on the show, simply tweeted, "no". That tweet was later deleted, but not before being retweeted thousands of times.

Lea Michele, Monteith's girlfriend both on-screen and off, however, did not tweet. A statement from the 26-year-old star simply asked for privacy "during this devastating time."

More reaction from the cast:
