Gossip Girl Leighton Meester sneaks in a bite of a juicy hamburger on the set of her hit CW show while filming at the Museum of the City of New York on Tuesday afternoon.

The 22-year-old actress joined co-stars Blake Lively and Penn Badgley to film scenes for an upcoming episode (also pictured below).

On last night’s episode of Gossip Girl, we found out who’s funeral it was – Bart Bass. An insider on the series hints to E Online that we’ve only just seen the beginning of Blair (Meester) and Chuck’s (Ed Westwick) relationship. They shared, “Chuck and Blair aren’t just the Gossip Girl couple of the moment. They are the core Gossip Girl couple of the series. So you definitely will see much, much more of them in the days to come. The dance has just begun.”

Take a peek at the preview for the next new episode below!
