Trouble in paradise! In Touch is exclusively reporting that Jennifer Aniston and Justin Theroux, who were once smitten red-carpet fixtures together, have been living separate lives since October.

“Justin left Jen three months ago when he went off to shoot the film On the Basis of Sex in Montreal and work on the Netflix series Maniac in New York,” a friend reveals. “He’s been living primarily at his apartment in Greenwich Village.”

And sources explain that two years after they wed, the marriage has crumbled. “Although they have put up a good facade of being a happily married couple, the opposite is true,” says the friend. But following her messy, high-profile divorce from Brad Pitt, 53, in 2005, Jen is reluctant to let go just yet.

“Jen and Justin have arguments about where they should live,” the insider continues. While Jen loves LA, where she has a home in the swanky Bel Air neighborhood, Justin clearly prefers NYC. “Jen can’t stand the weather in New York,” the insider says. “And she hates not having a car in the city to drive to wherever she needs to go.”

The East Coast–West Coast issue is just one of many differences that have divided the couple, who met on the set of Tropic Thunder in 2007 and became romantic after co-starring in 2012’s Wanderlust.

While friends would love to see them salvage their relationship and work things out, the insider says it’s a long shot. “It’s only a matter of time now,” the source concludes.
