Don't stand so close to me!

An insider on the set of Jennifer Aniston's 2011 flick Wanderlust, filmed this fall, tells the new Us Weekly, "It was an unspoken thing that you couldn't get within 20 feet of Jennifer. She surrounded herself with a ring of buffers at all times. She traveled with them from her trailer to the set and back."

(Aniston's rep calls the report "false," and says "Jennifer had a blast filming Wanderlust.")

Still, the actress, 41, may soon need to shed any personal-space issues, as another source says she is considering moving to the people-packed Big Apple (population: 8.4 million).
