Leighton Meester  and Adam Brody  took their two adorable pups out for a walk in NYC on Monday. The couple stayed close to one another during part of the walk — including when responsible dog owner Leighton picked up after her dog — but later split up as the actress headed to a tennis court to play with her furry friends. Leighton and Adam had been spending the first part of their Summer in the Big Apple while Leighton worked on her play, Of Mice and Men, on Broadway. However, the couple's future home base may be up in the air soon, as Leighton's play officially wrapped up on Sunday. The two had originally been living in LA, but it isn't clear if they will return to the West Coast anytime soon. Either way, Leighton's play went out with a bang as it broke the $1 million mark  for sales in its final week. This makes Of Mice and Men one of the bestselling plays of the year.
