Think you'd add something to that picture? Gossip Girl will be filming in the Hamptons this summer and Josh Schwartz wants you to be an extra. Well, he does so long as you are a SAG member and “own a wide variety of upscale wardrobe including, but not limited to, polished trendy, designer labels, elegant formalwear, single and double breasted suits in addition to tasteful shoes and accessories.” I guess GG’s fabulous fashion closet is only big enough for 5. The casting call is Saturday, from 1-4 at Pink Elephant and the show itself will be filming in Southampton June 18/19, and Upper Brookville on the 22/23. Better start brushing up on your bitchisms and UES acumen now!
