Where are they filming!?

Ok, so being an obsessed fan, i spend my days at the office searching the internet for the latest on where the girls are filming. today, i lucked out and found them in front of christies! it was a dream come true to see the ladies looking fab walking down 5th ave! But does anyone know how to find out where they are headed next? (i obviously didnt get my full fix today!)

Any insights would be very much appreciated!!
