UPDATE/ Ryan Seacrest just announced a new bit of information regarding the Twilight surprise during the Oscars:
"Just talked to one of the Oscar producers, that rumor that we've been hearing about.. I just confirmed a huge Twilight musical moment on tonight's show. They say it's act seven, so I think that's about halfway through the show. If you're a Twilight fan, you'll want to see that in the actual Oscar telecast".
Ryan added he's 'Team Wolf' btw..
