Never mind Where's Waldo ... where was Winona? Winona Ryder's absence from the Oscars Sunday night prompted questions over the state of her relationship with reported love interest Matt Damon (who was in Los Angeles to be a presenter with his pal Ben Affleck). USA Today reports that on Hollywood's big night Ryder was in Harrisburg, Penn., where she is making the movie "Girl, Interrupted." Not that things are going smoothly. Monday, the paper reports, Ryder slipped and fell on the set, injuring her knee. After being rushed to an emergency room and then X-rayed, Winona was back at work on Tuesday. No word on whether or not Matt sent flowers.
