Leighton Meester at Roger Vivier Party Pictures

Leighton Meester posed for photos during a cocktail party at shoe and accessories designer Roger Vivier's NYC store last night. The Gossip Girl actress has been sporting heavy bangs during her time away from set lately, but when she's in character as Blair Waldorf, the show's hair stylists are working around her fringe. Leighton was shooting with Blake Lively yesterday morning before heading out to the soiree, and she traded Blair's signature done-up style for minimal makeup and a fun J. Mendel dress before hitting up the boutique. Blake, for her part, was back in NYC after spending the weekend in Boston with her rumored new boyfriend, Ryan Reynolds. Blake visited Ryan as he shot R.I.P.D. on Sunday, which happened to be his 35th birthday, and to celebrate she sent her dog out adorned in balloons as a surprise.
