Hey, upper east siders, Gossip Girl here, and I have the biggest news ever. One of my many sources Melanie91 sends 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 quote "boarding school"? And just as suddenly, she’s back. Don't believe me? See for yourselves. Lucky for us, Melanie91 sent proof.Melanie91 Thanks for the photo, Mel.
