A glammed-up Blake Lively and Leighton Meester were spotted yesterday evening on set. The actresses sported cocktail attire and extrahigh platform heels as they taped a scene for the final season of Gossip Girl, which begins airing on The CW in October. The cast got back to work on the show last month, and were joined by 7th Heaven alum Barry Watson during a recent day of shooting. The actor will be playing Blake's love interest this season. Off screen, Blake still appears to be going strong with Ryan Reynolds. The pair spent some of Blake's final days before returning to Gossip Girl vacationing with her family in New York state. Blake wore a bikini during one of their days spent lakeside, and both she and Ryan were seen spending some time with Blake's nieces and nephews during the getaway.
