There was a story about them on last night intoducing clips for the finale. Jen and Michael weren't on themselves, though. I think your source is wrong, unless there is another sneak peek.
They had clips from the episode. They were clips that were NOT on the finale promo. It was great! they talked about how Jen and Michael are rumored to being together but how it's not true. THey also talked about how this episode is jam packed with romance and that the last minutes will leave us hanging like never before. WOW!!! I can't wait!!
