Hey Upper Ease Siders. Gossip Girl here. And I have the biggest news ever. One of my many sources, Melanie91, send us this: "Spotted at Grand Central, bags in hand: Serena van der Woodsen." Was it only a year ago our It Girl mysteriously disappeared for "boarding school"? And just as suddenly, she's back. Don't believe me? See for yourselves. Lucky for us, Melanie91 sent proof. Thanks for the photo, Mel.
