'Gossip Girl': What is Serena's secret?

My head’s been spinning with "Gossip Girl" news this week. First was word that Lisa Loeb is making a cameo on the show (who didn’t love her hit single "Stay"?). Then there were the overdose rumors and a first look at set photos from Lily’s wedding. It’s hard to focus on the issue at hand in this Monday’s episode: Serena’s secret.

In the previews, a horrified Serena is illuminated by a laptop. I think her secret will be a viral one (i.e. a sex tape — they’re all the rage) and Georgina will place it in Gossip Girl’s hands. It’s definitely juicy because the shame of it all leads S on a downward spiral in the May 12 episode (gasp --will she OD?). We already know Eric Van Der Woodsen’s secret—what could his big sis be hiding?
