Kristen Bell has been lending her voice as the narrator of Gossip Girl since the pilot episode in 2007. We were excited when we found out last month that the petite (pregnant) actress would be making a cameo in the series finale, Season 6, Episode 10 "New York, I Love You XOXO.” But until tonight’s episode actually aired, we didn’t know how excellent it would be to see her come to life on set.

So, what gives? Is she Gossip Girl? A long-lost cousin coming back to claim her share of an inheritance? (Oh, right, that’s been done.) Nope, she had a brilliant cameo that showed us that the Gossip Girl writers still have some fight left in them, despite the series wrapping.

Cameras zoomed in on Kristen, reading “Greetings Upper East Siders...” as usual, but in a super meta moment, she did it as an actress running lines. Not meta enough for you? She was reading with Rachel Bilson, star of GG co-creator Josh Schwartz’s other baby, The O.C. Aaand the two were practicing for a possible movie, based on Dan Humphrey’s writing.

Headbands off to that.
