EXCLUSIVE: Millions of 'Super Bowl'-watchers stuck to FOX last night to watch the blowout episode of 'Glee,' but no one was more surprised than Dina Lohan when guest star Katie Couric took a nasty swipe at her, calling the celeb mom and her dog losers.

"So much for the peace between the Lohan family and 'Glee,'" a family friend of Dina's told me after watching the episode.

If you need a refresher, the show just apologized for mocking Lindsay Lohan earlier this season. In the episode, Gwyneth Paltrow guest starred as a Spanish teacher and name-dropped the actress in a lesson, asking, "Lindsay Lohan is totally crazy, right?"
