Cory Monteith's estranged father has been left devastated after learning the tragic actor's remains were cremated on Tuesday (16Jul13) before he had a chance to pay his last respects to his dead son.

Monteith's mother, brother and girlfriend Lea Michele staged a private viewing and farewell in Vancouver, Canada a day after the British Columbia coroner wrapped up an autopsy on the Glee star's body - and his father wasn't invited.

Heartbroken Joe Monteith, who is divorced from Cory's mother Ann, tells he was informed of the cremation after it had taken place.

He says, "I always loved both my sons and am going to miss Cory very, very much. I'm saddened at the fact that I couldn't have been there to see my son before he was cremated."

Representatives for Monteith and Michele have yet to confirm the news of the cremation.
