Hilary Duff in Preview for Upcoming Gossip Girl Episode

The new trailer for the upcoming episode of Gossip Girl, “The Last Days of Disco Stick” has been released and it looks like it’s full of drama. After Hilary’s character Olivia Burke has a threesome with boyfriend, Dan (Penn Badgley) and roommate Vanessa (Jessica Szohr), things are totally awkward.

Now, it looks like there’s some kind of rivalry between Olivia and Vanessa, where Olivia is feeling as though Dan likes Vanessa more. What do you guy thinks? Are Dan and Vanessa really hitting it off, or is she just paranoid?

Tune in on Monday, the 16th to catch Hilary in the newest episode of Gossip Girl.
