The Gossip Girl threesome between Olivia (Hilary Duff), Dan (Penn Badgley) and Vanessa (Jessica Szohr) may have upset parents last week but its the threesome who have the issues this week as they deal with the morning after and the news that Olivia isn’t leaving after all. Tonight’s episode will focus on the three of them reconnecting and the unavoidable awkwardness after a night of recklessness.

But, believe it or not, that won’t be the highlight of tonight’s show. Instead, the show-stopper will likely be the performance from Lady GaGa in a 30 foot dress! You can check out a preview of GaGa’s performance and the rest of the show below!
