We're still shocked about the news of Cory Monteith's sudden death.
And we can't even imagine how hard this is on those who were closest to him.
But it's nice to see everyone is leaning on each other during this difficult time, and also taking this chance to remember the wonderful, happy Glee star they once worked with.
Cory clearly touched many hearts, and now those costars and coworkers have taken to Twitter to express their condolences.
Check out some of what they've tweeted:
Our thoughts and prayers are with Cory's friends and family!
