Hear any names on yesterday’s Gossip Girl Season 5, Episode 10: "Riding in Town Cars With Boys" that didn’t quite ring a bell? Fear not. We’ve got you covered with this handy little cheat sheet.

Karen Finley

Of course Serena’s Aunt Carol (Sheila Kelley) had Karen Finley impersonate her at her coming out party. Of course she did.

Karen Finley is a performance artist who’s known for her out-there installations, which often involve her own naked body and chocolate. She was one of the “NEA four,” four artists who had their federal grants revoked on grounds of indecency. That’s what happens when you cross CeCe (Caroline Lagerfelt).

Matthew Lynch

Yes, that tiny man talking to Lily was a real Women’s Wear Daily reporter. Anyone else wonder if Gossip Girl ever regrets hopping aboard the cameo train? They do tend to have a lot of them...
