Leighton Meester was arm-in-arm with her Monte Carlo costar, Luke Bracy, for a walk around Paris's Père Lachaise cemetary earlier today — get her look here. She seems to be getting along well with the other actors in her film, after enjoying on-set fun with Cory Monteith and Selena Gomez. Leighton stayed busy during her hiatus from Gossip Girl by also shooting The Oranges with Adam Brody. Some of her fellow Upper East Siders, though, are holding down the fort back in Manhattan. The season finale ended with Leighton's newly single character Blair taking off for a Summer adventure in France, and it looks like Leighton, who broke up with her own boyfriend, is doing the same.
