Twilights Out for Seacrest -- Pattinson Walks Off

Ryan Seacrest's radio show came to a screeching halt last night after he asked "Twilight" star Robert Pattinson the most controversial, hard-nosed question in the history of questions ... what's the deal with you and Kristen Stewart?



As soon as Ryan asked the question -- apparently forbidden by the Twilight powers that be -- Pattinson's cold-blooded handler flipped out and pulled Robert right outta the chair.

Robert remained charming as he got up and left ... but the bottom line -- he still left.
