Jane Lynch Delivers Warts & All Tribute to Cory Klugman's Son Be Damned

0-sim18gil

Jane Lynch just delivered a powerful tribute at the Emmys for her "Glee" costar Cory Monteith ... that definitely won't make Jack Klugman's son feel any better.

Jane pulled no punches during the speech ... reminding the audience Cory "wasn't perfect" -- and referred to his death as a reminder of the dangers of addiction.

Klugman's son felt the Emmys dissed his father by choosing to pay special tribute to Cory ... whose death he called a "self-induced tragedy."

Klugman's death was acknowledged later in the show during a montage.
