And now we have our answers!!!
It's still unclear what caused Cory Monteith's death, but it is known that he had been battling addiction issues.
And while many are speculating that an overdose might have been the cause, we'd hate to see his battle end this way especially since he was apparently fighting so hard.
He did recently reenter rehab this year for about a month, and he seemed to be doing well when he left.
And the Glee actor seemed to also be well-aware of the fighting he'd have to continue doing as a source revealed:
"He was super committed to getting sober. He would say this was his last chance."
"He was worried about the press around it. But he knew he had to do this because his life was depending on it."
Whether or not his addiction did play a role in his sudden death it was a huge tragedy to learn of this loss.
We hope he is now be able to rest in peace.
